Abstract: 1437172 Mechanical switches BORDER ES (DESIGN & DEVELOPMENT) Ltd 27 July 1973 [29 April 1972 23 Jan 1973] 20004/72 and 3437/73 Heading H1N An electrical switch comprises a housing 12 containing two pairs of contact arms and a linearly movable plunger 28 having cam faces 28a and 28b engageable respectively with the contact arms 18, 20 and 22, 24 such that movement of the plunger axially to the right relative to the arms causes deflection of the arms by the cam faces and closes normally open contacts 18, 20, and opens normally closed contacts 22, 24. Movement of the plunger to the left relative to the arms restores the arms to their normal positions, the resilience of the arms on the sloping cam surfaces providing the restoring force. In an alternative arrangement a conductive element on the cam bridges the contact arms to make connection between them when the plunger is moved. A latching device may be provided and comprises a cylindrical member 30 mounted in the housing for axial and rotary motion and having formed in its circumferential surface a slot having its side walls 34, 36 formed as a cam surface for engagement with or rider 38 secured to the switch housing. The cam surface has deep grooves 34a and shallow grooves 34b forming stable rest positions for the rider 38, such that when the rider is in the shallow grooves 34b the switch is in its normal position and when it is in the deep grooves 34a the switch is in the operated position with the resilient arms deflected. Operation of the plunger causes rotation of the cylindrical member 30 and displacement of the rider from the one groove it is in to the other groove, intermediate positions being unstable. In a further embodiment, Fig. 5, not shown, grooves are arranged in the cam faces which operate the resilient contact arms, the latter being shaped to snap into these grooves when they ride up the cam faces to provide a tactile indication of the operation of the switch.

An accumulator electrode consists of porous sintered metal impregnated with active material and a compound of titanium. If the sintered metal serves as the active material, for example iron, it is impregnated with a titanium salt and then with caustic alkali to precipitate titanium hydrate. If the sintered metal is inactive, for example nickel or iron rendered passive, it is first impregnated with titanium and then with electrochemically active substances such as cadmium or iron. Alternating layers of titanium and active material may be deposited in the sintered body by successive impregnations. The titanium and active material may also be precipitated simultaneously as hydrates in the porous body and the active material may consist of a mixture of cadmium and iron hydrates. In an example, a porous sintered metal plate is immersed in an aqueous solution of the chlorides of cadmium, iron, and titanium and then subjected to electrolysis in a bath of caustic soda to reduce the salts to hydrates. Specification 339,645, [Class 53], is referred to.
