摘要

A contactor for exciting in any order of a plurality of circuits, characterized by the depression of a rigid lamellar plate, caused by the subsequent depression of an external medium, preferably a key operated by the user or caused by predetermined programming, the displacement is achieved of the contact connection means so that having as many actuators as circuits must serve the device, once closed a circuit is kept closed while the pressure on another similar plate of the series does not release the previously pressed, either this pressure liberating due to the need to close another circuit, in which case the depressed plate will be the one belonging to the new circuit, or simply depressed any other flat button with a lighter effort than in the previous case but sufficient to produce the desired release, is say, that two circuits can never be closed in simultaneity of the contactor.
