ABSTRACT:
An electrical snap action switch for use in a temperature regulator has a movable contact assembly consisting of a conductive contact carrying arm movable between fixed stops and cantilevered within the switch housing, the contact arm being parallel to and cooperating with a Q-shaped snap-action spring, so that the arm carries the working current while the snap spring acts on the arm to make the switch monostable in operation between the stops.
