4 and 5, for example. It willalso be notieed that the spring a is held by its confined' relation to the parts b and m rather lot than being secured to either. The part m 1112a has a predetermined limit of play within body a--a' so that cooperative movement may be obtained.

The spring shown herein is a straight coil of wire when-not in working engagement with the parts, and the band I) is rectangular, and loosely fitted over thefl-ut-face'd. enlarged portion 3 of the thrust or operating member m. Twisting or turning of the band is prevented by the fiat f-hearing reliitions between it and member 'II'L, -a.nd bnid member is also prevented from turning by the fiat sides of its reduced ends. This makes a very simple eomb nntionof Ip'a-rts which will not ear out b nd or be;

come loose or detached, and the operating space occupied by said parts is'rednred to the minimum. As shown herein thesides of the body 3 of the push member .or bar in are recessed lengthwise at 8 to confine and back the spring at its ends, thereb preventing the ends of the spring, from springing or working .out of place and the open ends of the springihave fnlernni relations with the lugs 4.

Tu Fig. 12, I show a modified-form of the.

invention in which the sleeve or band .71 is. T adapted to become theactuating member.

The parts I), m and .x' may be embodled in a. pendant switch bud v,- or in njviill switch body, and they-may also-be utiI-izedin other snap action is desired.
