LATCHING: Also called pulse latching, a mode of operation in which the switch remains in a preselected position whenever the actuating voltage is removed or interrupted, and holds that preselected position until a voltage is applied to another position.
CUT OFF POWER CIRCUIT: This applies to a latching type switch only. A switch that has the ability to disconnect the actuator drive circuit so that D.C. current will not be consumed after switching has been accomplished.
