how to how to make mosquito coil control circuit

Latching Relay Circuit | REUKcouk- how to how to make mosquito coil control circuit ,The diagram above shows how such a relay can be used to make a latching relay circuitThe circuit has two buttons – one is a push to make which closes when pressed but is otherwise open, and the other is a push to break which opens when pressed but is otherwise closed When the push to make button is pressed, 12V goes across the coil energising the relay4 Ways to Control Electronic Relays - Make:Mar 19, 2018·When the relay is at rest (no voltage applied to the control circuit), the switched circuit is closed and current flows through the switched circuit When you activate the relay by applying an appropriate voltage to the control circuit, the electromagnetic coil in the relay activates and pulls the switch open, stopping any current flowing
