Industrial control switch is used frequently and has a complexed working environment. And it may be influenced by various interferences, so it is required to be strong and durable with easy operation and strong anti-interference ability. The circuit generates and forms trigger signal through touch signal input circuit. It triggers the bi-directional thyristor which will make the controlled circuit connected or disconnected. It has no reliable anti-interference circuit and its work is reliable. The picture shows the circuit. The circuit uses monostable trigger which is composed of NE555 to generate control pulse, and it uses bistable trigger which is composed of CD4013 as trigger control, and it uses bi-directional thyristor as control switch.
