GH-1A-12L datasheet relay


The GH-1A-12L is 1 Pole, 12V Relay.

A 12V relay is an electromechanical switch that is activated by an electrical signal of 12 volts. It consists of a coil, a set of contacts, and a mechanical mechanism that connects or disconnects the contacts when the coil is energized.

When the 12V signal is applied to the coil of the relay, it creates a magnetic field that pulls the contacts into the closed position. When the signal is removed, the contacts return to their original position. This allows the relay to switch high voltage and high current loads using a low voltage signal.


1. Superminiature, High power.
2. Low coil power consumption.
3. PC board mounting.
