Readily mountable thermostat

摘要

A thermostat device has control means movable between control positions on a base when a thermostat metal element moves with snap action in response to temperature changes. Angle-shaped mounting brackets of a relatively high strength metal material have respective legs fitted against a boss on the base periphery and a cup-shaped cap of a relatively more formable and more thermally conductive metal is fitted over the thermostat metal element on the base to enclose the noted legs of the brackets. Portions of the cup are deformed into openings in the enclosed bracket legs to draw the brackets firmly against the boss for securing the cap, brackets and thermostat metal element to the base, for conveniently and accurately locating the thermostat metal element in a desired control location on the base, and for permitting use of the brackets in mounting the thermostat device and use of the thermally conducting cap in transmitting heat to the thermostat metal element while reliably maintaining the control location of the element.
