Control mechanisms for electrical devices, capable of combining with a triple set of elastic springs 7-70-71, contact-holders of an open angular version, with vertices 7b-70b-71b of different arc, and a set of sliding keys 8-8' with 2 versions of sliding levers 10-10a-10'-10", a double version 10-10a in the form of inverse projections, and another triple version 10-10'-10" in the form of symmetrical projections, to compare single-pin, two-pin, and three-pin switching, crossing and pulsing mechanisms, making it possible, in all the previous versions, except for the 3-pin version, to use one of the clamped recesses of the central section of the casing, to incorporate a signalling pilot light. It is applicable to small electrical switching units operated by means of sliding key, with a blow-out and connection element based on a small flexible laminar contact-holder spring. <IMAGE>
