Abstract: 1,255,589. Thermal switches. MICRO DEVICES CORP. 4 March, 1970 [18 March, 1969], No. 10504/70. Heading H1N. A thermal cut-out released by a fusible pellet 22 comprises a conductive tubular casing 12 to which one conductor 18 is connected, the second conductor 20 being held in an insulating plug 16 and a movable contact 24 having resilient peripheral conductive engagement with the casing 12 is held in contact with the second conductor 20 by a compression spring arrangement. A relatively strong spring 52 acts between the pellet 22 and movable contact 24, discs 56 and 58 distributing the loading respectively, while a relatively weak spring 54 acts between the contact 24 and plug 16. When pellet 22 fuses at a predetermined temperature the spring 52 expands so that its force on contact 24 becomes less than that of spring 54, the contact 24 thus moves away from the head 40 of conductor 20 and breaks the circuit between conductors 18 and 20. Compound 42 seals the end of casing 12. In a second embodiment (Figs. 7 and 8, not shown) the insulating plug has a cavity (instead of the inward extension 36) to receive the head of the second conductor. In this case a pin-like member (92) extends from the movable contact into the cavity to engage the second conductor, and the weaker compression spring acts on the head of this pin (92), urging it against the member 24.
