To build To build On Off Touch Switch Circuit

Wireless Black 2 Gang 1 Way Touch Switch Touch Panel Switch 86

The fashionable mechanic switches are improved concerning of old technology. We want however many times to replacement some old switch or to check currents bigger than the durability of certain switches or simple we want something with modern appearance. For he and different reasons is important the up circuit. It is easy in the manufacture and the materials that use they exist everywhere.

Circuit diagram:

  • R1 = 3.3M
  • R2 = 3.3M
  • R3 = 10K
  • R4 = 1K
  • C1 = 10nF-63V
  • D1 = 1N4007
  • D2 = Red LED
  • Q1 = BC547
  • IC1 = NE555
  • RL1 = 12V Relay

Circuit Operation:

This circuit relies on the well-known timer IC 555 (IC1), which drives a relay of which the contacts play the role of switch. The metal surfaces can have what form we would like, but it should they are clean and near within the circuit. To be able to it changes situation it suffices touch soft somebody from the 2 plates. Plate MP1 with the intention to the contacts of RL1 close [ON], or plate MP2 with a view to the contacts of RL1 open [OFF]. The present that RL1 will check depended from his contacts. The Led D2 turns on when the switch they are in place ON and the contacts of RL1 closed. Two small pieces of metal can be utilized instead of MP1 MP2. Because MP = Metal Plate.
