ABSTRACT OF THE DISCLOSURE An electrical switching device is disclosed, which is particularly well adapted for use in a hold-up alarm system. The device comprises a casing having a longitudinal axis and two lateral openings symmetrically positioned with respect to the longitudinal axis and a push-button switch centrally mounted inside the casing, and having an actuating push- button coaxial to the casing. The push-button switch is connected in series with an electrical circuit so that this circuit is switched on or off when the button is pressed. The device also comprises a flexible blade extending transversally inside the casing, the blade having a central portion adjacent to the push button and two opposite ends; and manually operable device for squeezing the blade in such a manner as to cause it to bend and press onto the push button to activate the switch. The squeezing device includes a pair of actuating arms symmetrically mounted inside the casing, each of the arms extending across one of the lateral openings and having at least one portion that is movable inwards the casing to press against one of the ends of the blade whenever a pressure is exerted through one of the openings. The blade and arms are so dimensioned and positioned as to cause the blade to bend sufficiently to activate the push-button switch only when both of these arms are pushed in simultaneously.
