Disclosed is a cyclic mechanism for engaging or disengaging a switch with the stage of the cycle being determined by a height to which a first object is lifted relative to a second object. The mechanism has few moving parts, is inexpensive to manufacture, is reliable, can be incorporated into a wide range of devices or structures, and operates as an incident to raising or lowering a first object relative to a second.
