Do not use/store the products where it is subject to corrosive gasses such as H2S/SO2/NH3/HNO3/Cl3, and sea breeze. 2. Do not apply any force which causes deformation and deterioration. 3. Do not apply oil to the product. 4. Avoid direct sun. 5. Do not storage where visible dust is. Some types of loads have a large difference between steadystate current and inrush current, as shown in the following diagram. Select a switch with ratings suitable for the type of load. Select a switch with ratings suitable for the type of load. The higher the inrush current in the closed circuit is, the more the contact abrasion or shift there will be. Consequently, contact welding or shifting may occur, possibly resulting in short-circuits or burning. Flat cable connections • Please use it after confirming the cable is properly connected. Types of Load vs. Inrush Current Precautions for Safe Use I (A) ● Always observe the following cautions to ensure safety. Solenoid (× 10 to 20) Incandescent lamp (× 10 to 15) Mounting Before mounting, dismounting, wiring, or inspecting a switch, be sure to turn OFF the power supply to the switch, otherwise an electric shock may be received or the switch may burn. Motor (× 5 to 10) Relay (× 4 to 5) Wiring • Do not perform wiring when power is being supplied to a switch. Also, do not touch any of the charged terminals when power is being supplied. Otherwise, electric shock may be received. • Follow the instructions provided in Correct Use for all wiring and soldering work. Using a switch with improper wiring or soldering may result in abnormal heating when power is supplied, possibly resulting in burning. Contact Load Select suitable switch ratings after confirming contact load. If the contact load is excessive for the contacts, the contacts may weld or shift, possibly resulting in short-circuits or burning when power is supplied. 4 t Operating Atmosphere Do not use switches in atmospheres containing combustible or explosive gases. Arc or heat generated by switching may cause fires or explosions. Shock on Individual Switches Do not drop or disassemble switches. Not only will characteristics be jeopardized, but also damage, electric shock, or burning may result. Durability The durability of a switch greatly varies with switching conditions. Before using a switch, be sure to test the switch under actual conditions in the actual application and to use the switch within the switching operations causing no problem. If a deteriorated switch is used continuously, insulation failures, contact welding, contact failures, switch damage, or switch burnout may result. C3AW Trigger switch for DC Brushless tools Precautions for Correct Use Using Switches • When switches are actually used, unforeseen accidents may occur. Before using a switch, perform all possible testing in advance. • Unless otherwise specified, ratings and performances given in this catalog are for standard test conditions (i.e., +5 to +35°C, and +45% to +85% humidity). When performing testing in the actual application, always use the same conditions as will be used in actual usage conditions for both the load and the operating environment. • Reference data provided in this catalog represents actual measurements from production samples in graph form. All reference data values are nominal. • All ratings and performance values provided in this catalog are the results of a single test each rating and performance value therefore may not be met for composite conditions. • Output voltage changes due to the brush sliding along the top surface of the circuit board in the switch. When there is contact resistance between the circuit board and the brush, it goes into a state of high impedance, and the output voltage fluctuates. To prevent this from happening, a pull-up/down circuit can be implemented. Check the level of output voltage fluctuations and compatibility of this circuit with your application to determine if this switch fits your needs. Example of output voltage fluctuations Voltage Stroke 5 Please check each region's Terms & Conditions by region website.
