Abstract

The electrical limit switch is of small dimensions and it has a rigid body, and an protruding element (1) cooperating with an electrical conductor one end of which is connected to a first constant piece (6). When a means exterior to the electrical switch presses against the switches protruding element, the other end of the electrical conductor pierces a bulb (5) which is filled with mercury and which is in a contact with a second piece (7), so as to electrically connect these two pieces (6, 7) which are normally isolated when the protruding element (1) is in its normal position. The apparatus has a thick outer casing (10) which is impervious to mechanical shocks.
