THE RELAY - How It Works
The Battery Disconnect Relay is a mechanically latching switch that operates by the momen-
tary application of battery voltage to the coil terminals in one direction for latching (closed) or
the other direction for unlatching (open).
To close the relay, +12 volts is applied to the "I" terminal and ground to the "S" terminal of the
relay. When this is done, the plunger is pulled into the coil and the contacts are connected.
While this happens, the rod magnet suspended above the plunger is attracted (opposite poles
attract) to the top of the plunger by the magnetic field. See FIGURE 1
When the voltage is removed from the coil, the plunger gets pushed upward by the return
spring, but cannot move because the rod magnet is in the way. See FIGURE 2
