Potter and Brumfield Latching Relay Schematic

Here is a schematic of the Potter and Brumfield Latching Relay needed to operate electric linear actuators.
	Here is what the complete relay looks like. There are two circuits you need to wire: The micro switch circuits, and the relay (trigger) coil.
	These micro switches control the linear actuator. As the center rocker switch moves side to side, one switch will engage, and the other will disengage. Notice the two outputs that go to the actuator wires, and that they MUST be connected as in the diagram.
	This big plunger-type relay controls the center rocker switch that engages the micro switches. This is only a coil, and needs a +12V and a ground to operate. I prefer to have the +12V as constant, and use a push-button momentary switch to send it a ground. You MUST use a MOMENTARY switch, as the coil field will only need to trigger once, NOT continuously. If you prefer, you can use a constant ground and put the +12V thru the momentary switch, or even use the pulsed + output of an alarm or remote turn on lead to activate this field instead of a switch.
