manufacturer 4.5×4.5 4 pin DIP tact switch

  5A INSULATION RESISTANCE Measurements shall be made following Application of DC100V potential across terminals and across terminals and fuame for 1minute,100MΩ min 5B WITHSTAND VILTAGE AC250V、50HZ、1 min(imin(interrupting current≤500uA). AC250V、50HZ、5C CONTACT CIRCUIT Addition 1.5-2 time force on the top of the key strok and press the switch,DC50V100mA 100mΩ Max 5D SWITCH CONNECTION FLASH Addition DC5V on the two side of switch,at a speed of 3-5time a sec.to press the switch.The flash time between open not more than 10ms. 6.MECHANICAL EFFICIENCY 6A CONTACT STRENGTH The contact shall be capable of a rorce of 5N for 5 seconds in any directions. Switch electric andmechanical efficiency does not break 6B CONTACT JOURNEY 6C DRIVE FORCE Being measure at across spring piece and across 6D CONNECTION STRENGTH A force of 1N being appling in any directions of the switch connection partt.Switch mechanical efficiency does not break. 6E MECHANICAL LIFE Operatin at a rate of 30-50 cycles a minute. 以 Life:100000ycles 7.ENVIRONME NT----RESISTANT EFFICIENCY 7A CHANGE OF TEMPERATURE The first temperature shall be 70 ℃ ,3h and changed to-25℃,0.5h,5cycles of above test. 1. The appearance should not break. 2. Contact resistance ≤ 100 M Ω 3. Insulation resistance ≥ 100 M Ω. 7B HUMIDITY RESISTANT 40±2℃ in temperature and 90-95%RH,Ruring thetest time without load; After testing the temperature should be 24h. 8.IOINTING EFFICIENCY 8A SOLDERABILITY Temperature260±5℃;Duration;3±0.5S Solderability part should above 90% 8B SOLDER—RESISTANT Warm-up temperature:100℃,40S, Froth height of assist solder should under board and switch electric and mechanical efficiency does not break. 8C JOINTING—RESISTANT Jointing temperature: 260 ± 5 ℃ ,Duration of immersion: 5±1S. efficiency does not break 8D NORMAL JOLNTING TIMES ≤2times
