Mains Remote Switch

Mains Remote Switch
Mains Remote Switch
This compact design forms a remotely operated switch that receives its control signal via the mains voltage. The switch is operated using the ‘mains remote transmitter’ described elsewhere in this issue. With this transmitter, a switch should be connected between pins 1 and 2 of K1. Depending on the application, this must be either a press contact or a make contact.The idea of the ‘mains remote switch’ is that a relay is energised in order to connect the mains voltage on K1 through to K2.
