The electric switch circuit of touch type (5)

Published:2011/6/30 5:27:00 Author:Seven | Keyword: electric switch, touch type | From:SeekIC

The electric switch circuit of touch type in the following introduction is in 2-line connection, which can easily replace the ordinary mechanical switch. The circuit consists of the time-based integrated circuit IC(NE555), thyristor VT, rectifying diodes VD1 and VD4, regulated diode VS and so on. Elements selection. R2 is chosen as the 1/2W carbon film resistor, and the other resistors can be 1/4W carbon film resistor. C1 can be the aluminium electrolytic capacitor with the withstand voltage higher than 16V, C2 can be the ordinary dacron capacitor. All of VD1~VD4 are chosen as the 1N4007 rectifier diode.
