ABSTRACT:
A bounce-free acceleration switch includes a resiliently mounted movable contact (14) which cooperates with a counter contact (15). The kinetic energy of the movable contact (14) is transmitted through an impact body (16) to a resiliently mounted massive body (17) which, when swinging back to its rest position, engages a stop (18). Re-transmission of the kinetic energy from the massive body (17) to the impact body (16) and thus to the contact couple (14, 15), which would cause contact bouncing, is prevented by providing a spacing (s) between the massive body (17) and the impact body (16) in the rest position of the apparatus, and by the fact that during the deflecting and swinging-back movement of the massive body (17) the impact body (16) returns towards its rest position and is therefore not hit again by the massive body (17).
