Abstract

An operating mechanism for the steam sensor switch of a water boiling vessels enables the condition of the steam sensor to be set by operation of a push-button. The mechanism comprises an operating member (4) which is coupled to the trip lever (3) of the steam sensor switch (2) for moving the same to determine the condition of the switch and an actuator (10) for moving the operating member. The actuator is movable transversely to the operating member and has an end portion which, when the actuator is depressed, moves into an aperture (6) in the operating member where cams (13, 14) on the actuator co-operate with cam follower surfaces (7, 8) of the aperture. On one side of the aperture the cam on the actuator is a simple inclined surface (13) for moving the operating member in a first direction and on the other side of the actuator the cam (14) is a pivotally mounted member which is compliant for accommodating movement of the operating member in said first direction but has only limited pivotal movement in the opposite direction. A first depression of the actuator brings one of the cams into play to move the operating member in a first direction and a second depression, the actuator being spring loaded and returning to its start position between successive depressions, causes the other cam to come into play to move the operating member back in the opposite direction.
