Here is the circuit diagram of an automatic touch plate controller using NE555 IC. The circuit turns on a relay when anyone touches the input metal plate for a short period of time. After then it switch off the relay or controlled device automatically. This circuit can be connected to calling bells, Buzzers, small toys etc.

We can connect toy motors to this circuit through a SL100 transistor, where we can avoid D1 and D2 Diodes.
