For any given state of the FLIP-FLOP touching the corresponding set of contacts will make the circuit to reverse its state of balance and in effect toggle the switch. As a switch is used a relay ...

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 ...

The relay-actuation side of the circuit needs only a small amount of current, so you can use a low-amp switch and small-gauge wire (even on long runs) to hook it up to the relay. For the electric ...

Different industries use a relay switch to control circuits via an independent low-power signal. This situation also happens when one signal must control several circuits, as seen in warehouses ...

This circuit uses electromechanical relays to retain its state indefinitely ... some form of flip-flop that responds to a pushbutton switch or other control input. These all have volatile memory ...
