Abstract
890,064. Thermal switches. MICHEL, J. Oct. 7, 1960, No. 34500/60. Class 38 (5). [Also in Groups XIII and XL (b)] A snap-acting bimetal disc or strip B bears a silver or platinum switch contact C 1 and has two heater resistances printed on a flexible pellicle of phenol-based epoxy resin or cured polyester (or on a pair of such pellicles) stuck to the bimetal. The first heater bends the bimetal to a position near that for snapaction but the bimetal does not snap to the operating position until a current passes through the second heater R 2 . The first heater may be on the same pellicle and side of the bimetal as the second heater R 2 or on a separate pellicle at the other side, Fig. 2b (not shown). The heater R 2 may be in circuit with a photo-electric cell (see Group XL (b)), a thermocouple or a device responding to a chemical factor, for producing a current so that the bimetal snaps to switch on apparatus connected between a holder H and a fixed contact with which the contact C 1 cooperates. The apparatus is switched-off when the current ceases in R 2 . Reference has been directed by the Comptroller to Specification 792,145.
