Abstract
A thermostat has a cup-shaped insulating base open at one end, a pair of terminals ultrasonically secured in the bottom of the base precisely locating respective stationary contacts within the base and having portions thereof extending outside the base, a flat metal element carrying movable contacts for engaging the stationary contacts, a flat metal motion transfer element secured to the movable contact element and having an extending portion precisely located adjacent the open end of the cup-shaped base, a spring mounted in the base biasing the movable contact element to engage and interconnect the stationary contacts, a dished thermostat metal element disposed in the open end of the base and movable with snap action in response to selected temperature change to engage and move the extending portion of the motion transfer element to move the movable contact element against the spring bias to disengage the stationary contacts, a thin electrically insulating film disposed over the thermostat metal element, and a lid secured over the open end of the base mounting the thermostat metal element in the open base end, the motion transfer element having a slit therein permitting compression of the extending portion thereof to adjust its spacing from the thermostat element for calibrating the thermostat.
