Abstract
A construction for a single pole double throw thermostatic switch of the type having a bimetallic disc which communicates with a resilient contact arm to alternatively effect electrical continuity between the arm and a pair of fixed contacts, and a method of assembling and adjusting the same. One of the fixed contacts comprises a bendable arm so that the gap between the fixed contacts is adjustable by bending the arm prior to final assembly of the switch. Because the gap is set prior to the final assembly of the switch, substantial increases in precision and reliability are realized since the contacts may be observed during setting thereof. Furthermore, the necessity for an external gap setting adjustment screw on the switch is eliminated.
