ABSTRACT:
A condition responsive electrical switch is provided with a housing, and means is movable in the housing between opposite positions for controlling the flow of power through the switch. Means is pivotally movable in the housing for effecting actuation of the controlling means between its opposite positions, and means is operable generally in response to a certain condition for driving the actuation means to pivot it and conjointly move the controlling means toward one of its opposite positions. Means is selectively operable for biasing the actuation means against the driving means to also pivot the actuation means and effect conjoint movement of the controlling means toward the other of its opposite positions.
A method of operating a condition responsive electrical switch and a control system are also disclosed.
