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).
