Therefore, be sure to keep within the conditions given below. • Manual soldering: Use soldering irons (max. 350°C, within 3 seconds) capable of temperature adjustment. This is to prevent deterioration due to soldering heat. Care should be taken not to apply force to the terminals during soldering. (More than one second interval is required to apply heat at each terminal.) Please consult us if you intend to use a soldering iron that exceeds 60 W. ■ Mounting • To secure the wire leads type switch, please use M3 small screws on a flat surface and tighten using a maximum torque of 0.29 N·m. Be sure to verify the quality under actual conditions of use because the switch plastic might be deformed according to that the kind of the screw (size of screw head etc.), the diameter of the washer and the presence of washer. And use of adhesive lock is recommended to prevent loosening of the screws. When using an adhesive, care should be taken not to invade the adhesive into the switches. • Be sure to maintain adequate insulating clearance between each terminal and ground. • The positioning of the switch should be such that direct force is not applied to the plunger or actuator in its free position. The operating force to the plunger should only be applied in a perpendicular direction. • When slanted press operation is applied to pin plunger type switches by an operation cam, the endurance life may greatly vary depending on the use of grease for sliding, operation angle, operation speed, operation frequency, press amount of the pin plunger, cam material, cam shape, cam surface condition, etc. Therefore fully verification by using the actual equipment in advance should be implemented. • After mounting please make sure no pulling load will be applied to the switch terminals. ■ Cautions regarding the circuit • In order to prevent malfunction in set devices caused by bounce and chattering during the ON-OFF switch operation, please verify the validity of the circuit under actual operating conditions and temperature range. • When switching inductive loads (relays, solenoids, buzzers, etc.), it is recommended that contact protection element such as diode, varistor, etc., is introduced to prevent contact failure caused by electric discharge. ■ Please verify under actual conditions. • Please be sure to conduct quality verification under actual operating conditions in order to increase reliability during actual use. ■ Selection of switch • Please make your selection so that there will be no problems even if the operating characteristics vary up to ±20% from the standard values. ■ Oil-proof and chemical-proof characteristics • Do not use alcohol-based solvents. • The rubber cap swells when exposed to oil and chemicals. The extent of swelling will vary widely depending on the type and amount of oil and chemicals. Check with the actual oil or chemicals used. In particular, be aware that solvents such as freon, chlorine, toluene, etc., cannot be used. ■ Operation environment • Although continuous operation of the switch is possible within the range of ambient temperature (humidity), as the humidity range differs depending on the ambient temperature, the humidity range indicated below should be used. Continuous use near the limit of the range should be avoided. This temperature-humidity range does not guarantee permanent performance. ■ Others • Do not handle the switch in a way that may cause damage to the sealing rubber cap. • Please remember that this switch cannot be used under water. Also, pleased be warned that switching and sudden temperature changes with the presence of water droplets can cause seepage into the unit. • Keep away from environments where silicon based adhesives, oil or grease are present as faulty contacts may result from silicon oxide. Do not use in areas where flammable or explosive gases from gasoline and thinner, etc., may be present. • When using the lever type, please be careful not to apply unreasonable load from the reverse or lateral directions of operation. • Do not exceed the total travel position (TTP) and press the actuator. This could cause operation failure. Also, when switching at high speed or under shock even within the operation limit, the working life may decrease. Therefore, please be sure to verify the quality under actual conditions of use. • Please make considerations so that the switch does not become the stopper for the moving part. • Do not use the switch which was dropped by mistakes when handling. If it is used, abnormal operation characteristics and sealing performance may occur. • In case of applying coating to movable parts (actuator, plunger, etc.), the quality of the product is not guaranteed because it may cause a product failure. • In case of cleaning a switch, the quality of the product is not guaranteed because it may cause a product failure. • Do not apply ultrasonic vibrations and high frequency vibration to a switch because it may have an impact on the characteristics of the switch. • Please do not constantly apply a tensile load to wire leads when fixing them.

The switch case may deform depending on the type of screw (screw head diameter, etc.), the size of the washer, and the use or non-use of a washer. Therefore, please confirm the appropriate torque of actual conditions. Also, it is recommended that adhesive be applied to lock the screws to prevent loosening of the screws. When doing so, please be careful not let any adhesive get inside the switch. ABJ (BJ) switches ABS (BS) switches ABV (BV) switches Screws M1.2 M2.3 M3.0 M2.3 M3.0 Tightening torque Not more than 0.098N·m Not more than 0.29N·m Not more than 0.29N·m Not more than 0.29N·m Not more than 0.49N·m 2) Fixed pin type To secure the switch unit, thermally crimp or press-fit the mounting pins. If the pins are to be press-fitted, install a guide on the opposite surface to the mounting pins to prevent them from slipping out of position and developing play. 3) Be sure to maintain adequate insulating clearance between each terminal and ground. 4) The positioning of the switch should be such that direct force is not applied to the pushbutton or actuator in its free position. The operating force to the pushbutton should only be applied in a perpendicular direction. 5) The standard value of overtravel used should be within the range of 70% to 100% of the rated OT value. 6) When soldering the BV type turquoise switch or the immersion protected type of the BJ and BS type switches, the sealing material sometimes forms a lump or bulge at the base of the terminal or lead. Be sure to allow enough space for this when attaching the switch. ■ Soldering operations 1) Manual soldering: Perform soldering in less than 3 seconds with maximum 350°C iron. Care should be taken not to apply force to the terminals during soldering. We recommend a soldering iron with temperature adjustment in order to prevent poor quality soldering. Please consult us if you intend to use a soldering iron of 60 W or higher. 2) Terminal portions should not be moved within 1 minute after soldering. ABJ (BJ) switches ABS (BS) switches ABV (BV) switches Soldering time Within 3 seconds Within 3 seconds Within 5 seconds –1– ■ Selection of the switch Allow for up to ±20% variation of the specified characteristics values to compensate for long term operational wear of the switch in your design. ■ Cautions regarding use 1) When switching inductive loads (relays, solenoids, buzzers, etc.), an arc absorbing circuit is recommended to protect the contacts. 2) If switching of the contact is synchronized with the phase of the AC power, reduced electrical life or welded contact may occur. Therefore, test the switch while it is operating under actual loads for this condition. If found, you may wish to take corrective action in your design. 3) In the slow or high speed operating condition, the electrical life might be greatly reduced depending upon the switching load. Please consult us before use. 4) Using lever type in do not condition, there is the concern that the flexible part may be impeded and return movement may not be possible. In this situation take the following precautions: • Select a product of higher OF or use a leaf type lever. • Attach a protective cover to the lever. 5) If the leaf lever type switch is excessively pushed (pushed further than the operational limit position) or switching is done at high speed or is accompanied by the impact, the lever will break. Please be careful. Also, be careful with the short roller lever type ABV (BV) switch as improper return may result from pressing too much. ■ Protection from dust, water and corrosive gas 1) The pin button and the space around the body cap Turquoise switches are sealed with elastic material, the terminal portion is integrally molded. This prevents dust entry and protects the switch against corrosive gases. Wireleaded types are recommended for applications subject to water or oil splash. However, avoid soaking these immersion protected types in oil or water, because those types are not of completely oil tight construction. 2) Switch operation or rapid temperature change while water droplets are on the switch may cause the water invasion inside the switch because of breathing action on condensation. Especially do not use switch in a bath. If sources of silicon gas are existing in the vicinity of the switch (silicon rubber, silicon oil, silicon coating, and silicon filler, etc.), silicon gas (low molecular siloxane, etc.) will be emitted and it will get into the product due to the permeability of the plastic. If the switch is used or stored in such an environment, silicon compound might generate on the contacts, cause the and faulty contacting. Therefore, please do not use sources that can emit silicon gas in the vicinity of the switch. Do not use in areas where flammable or explosive gases from gasoline and thinner, etc., may be present.
