Single Pole Double Throw Thermostatic Switch

View page
US Patent:
43397387, Jul 13, 1982
Filed:
Apr 30, 1981
Appl. No.:
6/259241
Inventors:
Robert J. Colavecchio - Johnston RI
Assignee:
Elmwood Sensors Inc. - Cranston RI
International Classification:
H01H 3752
US Classification:
337354
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.
