Abstract

Emergency button to hook, comprising a metal body for mounting on a panel by means of a threaded ring and for fixing a contact element, a slider capable of receiving an external operator body at one end and presenting two transverse grooves for effecting the coupling with a U-shaped spring attached to the body, at the end of the stroke of the slider, said grooves imparting to the section of the slider a cam-like shape, so that by a rotation thereof it is obtain its detachment from the spring, a washer for the transmission of the movement of the slider to the contact element and means apt to return the slider to the initial position when it comes detached from the U-shaped spring, characterized by the fact that the slider is divided into two parts that can perform a mutual rotation but not a relative axial sliding, and more precisely a slider and a key switch, and the key switch connected to the washer for the transmission of the movement to the contact element by determining together with the switch itself two transverse grooves for the engagement of the slider on the u-spring and for the subsequent disengagement thereof by turning the key switch, and that such means for returning the slider to its initial position are constituted by two spiral springs, one of which is interposed between the slider itself and the fixed operating body and acts in the direction of causing the disengagement and return of the slider outwards, and the other of which is interposed between the slider itself and the key switch and acts to impart the switch a turn capable of returning it to the initial position.
