Switch Operation and Taping
1.Use Tweezer or ball point pen for operation
2.Flux cleaning should be done without removing the Tape.
3.If the Tape is removed,it adhered less than before when it is placed back on ,possibl causing flux inflow.
4.Do Not Remove Tape sealed before Reflow Processing.
5.Ultasonic cleaning not recommended without Tape sealesd
*Keep all actuators inOFFposition during soldering and cleaning process.
*Any flux enters the switch may influence contact function.
