Style This specification describes ”DOUBLE ACTION SWITCH”, mainly used as signal switch of electric devices, with the general requirements of mechanical and electrical characteristic. 1.1 Operating Temperature Range : -20 ~+70 1.2 Storage Temperature Range : -30 ~+85 2. Current Range: 50mA, 12V DC 3. Type of Actuation: Double Action Tactile Feedback 4. Test Sequence: ITEM DESCRIPTION APPEARANCE TEST CONDITIONS REQUIREMENTS 1 There shall be no Visual By visual examination check without defects that affect the Examination any out pressure & testing serviceability of the product. Applying a static load twice the actuating fore to actuator. Contact Measurements shall be made with a Resistance 1 kHz small current contact resistance meter.(20mV 50mA max) Measurements shall be made Insulation following application of 100 V DC Resistance potential across terminals and across terminals and frame. Dielectric 250 V AC(50Hz or 60Hz) shall be Withstanding applied across terminals and across Voltage terminals and frame for 1 minute. Lightly striking the actuator at a rate encountered 3 to 4 operations per sec, bounce shall be tested at “ON” and “OFF” Bounce 2 ELECTRIC PERFORMANCE 100m Max 3 100M Min 4 There shall be no breakdown or flashover 20 m seconds Max. 5 5V DC 5K H01 sales@greatecs.com www.greatecs.com 2 Multi-Direction Switches SMT Double Action Switch MB6 Series Operating 6 Force Stroke Refer to part on drawing - 7 Stop Strength Placing the switch such that the direction of switch operation is vertical, a static load of 3 kgf (29.4N)shall be applied in the direction of stem operation for a period of 15 seconds 1 Contact Resistance: 10 Max 2 Insulation Resistance: 10M Min 3 Bounce: 20 m seconds max 4 Voltage: AC 250V 1minute MECHANICAL PERFORMANCE Min 1 Shall be free from pronounced backlash and falling-off or breakage terminals 2 Contact Resistance: 8 Solder Heat Resistance SMT Type~MB6 Series 10 Max 3 Insulation Resistance: 10M Min 4 Bounce: 20 m seconds max 5 Voltage: AC 250V 1minute Min Shall be vibrated in accordance with Method 201A of MIL-STD-202F Range of oscillation:10 to 55 Hz 1)Swing distance =1.5mm 2)Frequency: 10-55-10Hz in 1-min/cycle. 1 Contact Resistance: 10 Max 2 Insulation Resistance: 10M Min 3 Bounce: 20 m seconds max 4 Voltage: AC 250V 1minute 9 Vibration 10 Shock 3)Direction of oscillation: Three mutually perpendicular directions, Min including the directions of stem travel. 4)Test time: 2 hours each direction Shall be shocked in accordance with Method 213B condition A of MIL-STD-202F 1)Acceleration; 50G 2)Action time:11±1m seconds 3)Testing Direction: 6 sides 4)Test Cycle: 3 times in each direction Ditto H01 sales@greatecs.com www.greatecs.com 3 Multi-Direction Switches SMT Double Action Switch MB6 Series 11 Operating Life Measurements shall be made following 1 Operating force:±30% of the test forth below initial force 2 Contact Resistance: 1 5mA,5 VDC resistive load 10 Max 2 Applying a static load the operating 3 Insulation Resistance: force to the center of the stem in the 10M Min direction of operation 4 Bounce: Static Load OF Max. 20 m seconds max 3 Cycle of Operation 5 Voltage: AC 250V 1minute 30,000 cycles Min DURABILITY Min Following the test set forth below the sample shall be left in normal Resistance temperature and humidity conditions for 1 hour before the 12 Low Tempera- ture measurements are made: 1 Temperature:-30±2 WEATHER-PROOF 2 Time: 96 hours Following the test set forth below the sample shall be left in normal temperature and humidity conditions Heat for 1 hour before the measurements Resistance are made: 1 Temperature:85±2 2 Time: 96 hours 1 Contact Resistance: 10 Max 2 Insulation Resistance: 10M Min 3 Bounce: 20 m seconds max 4 Voltage: AC 250V 1minute Min 13 Ditto 14 Humidity Resistance Following the test set forth below the sample shall be left in normal temperature and humidity conditions for 1 hour before the measurements are made: 1 Temperature:40±2 2 Relative Humidity: 90~95% 3 Time: 96 hours Ditto 5.
