Changeover Relay Circuit

The pole of the relay will connect with the ground line which must be common to the changeover circuit and the ic 555 circuit both.

Changeover relay circuit.

The most common changeover function relays are produced to switch a single feed line usually positive position 30 between two active functions in a circuit the relay is switched manually via a toggle push switch or remotely through the circuit. The supply to the ic 555 circuit should be from the battery and the supply to the changeover circuit should be from an ac dc adapter. A polarity controlled relay needs changeover switches or an h bridge drive circuit to control it. The circuit diagram shown here is of a automatic changeover switch using ic ltc4412 from linear technologies.

In another type a ratchet relay has a ratchet mechanism that holds the contacts closed after the coil is momentarily energized. 12v changeover relay wiring diagram wiring diagram is a simplified customary pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the capacity and signal associates with the devices. The relay may be less expensive than other types but this is partly offset by the increased costs in the external circuit. The next concept makes an attempt to create a simple relay changeover circuit with zero crossing detector which may be used in inverter or ups changeover applications.
