(57) A push-button contactor (10) for activating call signals in push-button panels, particularly
for intercommunication and video-communication systems, comprises a housing having
a body (11) to which are fastened a first blade (14) and a second blade (15), both
made of an electroconductive material, projecting within the housing, and provided
with respective contact pins (16,17) engageable and solderable in respective holes
of the printed circuit for connecting to desired electroconductive tracks. The contactor
comprises an actuator stud (18), slidable in guide means made on said housing and
provided with a cam-shaped surface cooperating with a corresponding surface of the
first blade (14) in order to elastically draw it against the second blade (15), from
a rest position to a work position. The contactor also comprises elastic bias means
(25), for withdrawing said stud (18) from its work position to its rest position,
reacting against a push-button which axially engages the stud.
