Abstract
A control switch unit adaptable for a number of different purposes has a fluid-filled flexible-walled capsule acting within a housing on a pivoted operating lever arranged to operate a switch located in the housing on the other side of the pivot axis of the lever from the capsule, the lever being biased by a cam-adjustable tensioning spring acting on the opposite side of the operating lever from the capsule and the switch. Further components such as a manual switch-off control, a pilot lamp operable by an auxiliary switch, or a capsule heater, can be added without rearrangement of the basic unit.
