Abstract

1312399 Thermal switches GENERAL MOTORS CORP 4 Nov 1971 [23 Nov 1970] 51284/71 Heading H1N A thermally responsive switch comprises a housing 10 having therein thermally sensitive material 18, a resiliently deformable hollow plug 20 and resilient contact arms 34, 36 carrying contacts 38, 40 which are normally separated by a spacer 42 but which are engageable at a predetermined temperature by deformation of plug 20 due to expansion of material 18 at the predetermined temperature. Material 18 is wax which at the predetermined temperature turns into liquid and in doing so expands.
