Abstract

366,211. Tumbler switches. ARNOLD, C. L. and M. K. ELECTRIC, Ltd., Wakefield Street, Edmonton, London. Dec. 12, 1930, No. 37542. [Class 38 (v).] A tumbler switch has an actuating member 14 and a contact-member 11 pivoted at 10 to the bridge. Pins 17, 18 are carried respectively by the actuating and contact members and are embraced by an endless coiled spring 21. A plate 24 has a slot 25 which engages the pin 17, and a slot 26 which engages the pin 18. A third slot 29 allows for movement of the plate relative to the pin 10. Extensions 27, 28 engage the underside of the bridge during the sliding action of the plate. In action, the pin 17 moves the plate 24 causing the end of the slot 26 to move the pin 18 thus positively moving the contact-arm 11 across the deadcentre. Extensions 22, 23 on the contact-arm engage the bridge to limit the movement in each extreme position. Specification 350,615 is referred to.
