HowItWorks

A relay is an electrically actuated switch.

1. Coil: Terminals 85 and 86 are connected to a coil.

Applying 12 volts to these terminals energizes the

coil turning it into an electromagnet.

2. Switch: Terminals 30, 87 and 87a are actually

part of a single pole, double throw (SPDT) switch.

Terminal 30 is the common lead. The switch is

spring loaded so that 30 and 87a are connected

when the coil is not energized. When the coil is

energized, the switch is “thrown” and terminals 30

and 87 are connected (Fig. 484).
