This is a simple clap switch circuit with high sensitivity. The only unusual component is the single coil latching relay. While there are numerous means of generating the latching function, the ...

A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader ...

Electroswitch control switch relays combine the function of a control switch with a remote-controlled solenoid allowing one device to do both the manual and supervisory control function in the control ...
