Abstract

138,866. Comboni, G. Jan. 30, 1920. Snap-action switches have the contact member 2 which moves parallel to the base pivoted at 4 and connected by a spring 8 to the operating lever which is pivoted at 3 and moves between the base and a raised guide-plate 7. By moving the handle over to the other extreme position, the spring is taken over the dead-centre position and acts to withdraw the contact member rapidly from the fixed contact 12. In another form, constituting a two-way switch, a contact plate 2 and an operating lever 1 are both pivoted on the same pivot 3<1>, and the plate is slotted to receive pins 11, 11<1> upstanding from the lever. A spring 8 connects the pin 11 to a fixed pin 10, and springs 8' are arranged between the pin 11' and fixed pins on the contact plate. Reference has been directed by the Comptroller to Specification 15648/88.
