Abstract

1. Press switch for telecommunication engineering, especially for telephone technology, in which a button head (2) with a button shaft (3) is fitted in a casing (1), and in which plastic springs (10, 11) are accommodated between the end of the button shaft (3) and the contact springs (12, 13) in such a way that, when the button head (2) is pressed, the contact springs (12, 13) are indirectly operated via the plastic springs (10, 11), characterized by the fact that the plastic springs (10, 11) and the contact springs (12, 13) with their counter contacts (18) arranged on contact strips (16, 17) are attached to a plastic part (8) fixed under the casing (1), and that the actuating point of the end (21) of the button shaft (3) for the plastic springs (10, 11) and an actuating projection (20) moulded to the plastic springs (10, 11) for the contact springs (12, 13), viewed in the sense of length of the springs (10 through 13), are arranged at a distance from the contact points (18, 19).
