Abstract

1. An electro-mechanical switch for telephone apparatus, comprising a base part (1) made of insulating material and in which contact springs (2) in the form of leaf springs are arranged one beside another in parallel spaced planes so as to cover one another as regards their outline, the contact springs being in each case firmly clamped in the base part (1) at one end (3) and at the other end (4) can be elastically deflected at right angles to their plane of orientation by means of a control slide (7) which is guided so as to be linearly movable on the base part (1), characterised in that on the base part (1) the guide path of the control slide (7) is oriented parallel to the longitudinal direction of the contact springs (2) and the control slide (7) is provided with rigid, essentially parallel bars (8) which engage between the contact springs, parallel to the contact springs (2) from the deflectable ends thereof ; that on their side surfaces (11) which face towards the deflectable contact springs (2), the control bars (8) are in each case provided with both a sloped contact surface (13), which protrudes from the plane of the respective lateral surface, and also with a deflecting surface (12) which adjoins the contact surface and extends at a constant distance from the lateral starting plane (11) ; that in the vicinity of their free ends (4), the deflectable contact springs (2) are in each case provided with a driving cam (14) which protrudes at right angles to the deflecting surface (12) of the adjacent control bar (8), and have an elastic prestress (P1) which is oriented in the direction of the driving cam ; and that adjacent the free ends (4) of the deflectable contact springs (2), in each case from the side of the deflecting surface (12) of the adjacent side surface of the control bar (8), a counter-contact (6) is provided which has a parallel-extending, rigid contact surface and is fixed to the base part (1).
