The single-way SCR simple touching switch circuit

Published:2011/7/8 0:43:00 Author:Seven | Keyword: single-way SCR, touching switch | From:SeekIC

In the experiments, the writer found that the control pole of single-way MCR100-8 is conducting with a hand touch without the forward voltage, therefore, the writer designed a simple touching switch, see as the figure. By one touch, the metal chip is open, SCR1 is conducting, and the load is getting power. And with another touch, the metal plate is closed, SCR2 is conducting, relay J is getting power and working, K is cut off, the load loses effect. After SCR is cut off, the capacitor discharges to relay J, which keeps the relay closed for 4 seconds or so.
