A fluid bulb-sensing type thermostat having a capillary tube from the sensing bulb connected to an inlet port of a fluid pressure sensing chamber defined in part by an expansible diaphragm which moves in response to fluid pressure in the chamber from the bulb to actuate a snap-acting switch. The diaphragm is mounted on a plate which is cantilevered from the thermostat housing, and the at-rest position of the plate with respect to the housing is adjustable by a cam against which the free end of the plate is biased, for calibrating the thermostat. |
