Switch Operation and Taping
1. Use Tweezers 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,possibly causing  flux inflow.
4. Sealed switches withstand aqueous,detergent and isopropyl alcohol washing .
