Abstract
The invention provides an axially actuating tactile electrical switch comprising a casing; a plurality of independent fixed electrical contacts arranged in a base of the casing, and a movable electrical contact comprising a peripheral portion resting on a portion of a fixed peripheral electrical contact and a central portion movable vertically downwards; a single piece actuating body made of elastic material comprising a peripheral portion, an actuating central part comprising a lower portion for actuating the movable electrical contact, and an upper portion for receiving an actuating force, forming a casing comprising an upper cover having a hole whereby a free upper end section of the upper portion extends axially; the cover has an internal retaining surface; and the actuating body has an abutment surface cooperating with the internal retaining surface of the cover to determine an upper rest position of the actuating body with respect to the casing.
