Abstract: An electrical control or signaling device such as a push button or lamp includes a body which is fixed on a support wall and a baseplate for receiving contact blocks. The baseplate 20 houses a slide 30 and a manipulation screw having arms 33 and 34, acts on the slide 30 to translate the slide. The arms 33 and 34 have sharp edges or points (A1, A2) which act against the support wall and are displaced within a plane (P3) which is perpendicular to the plane S of the wall.

Abstract: An electrical controller signaling device such as a push-button which is fixed on a wall. The body of the push-button is inserted in an orifice in the wall and is mounted to the wall by means of a baseplate on the other side. A contact block is fixed to the baseplate using a rigid positioning and holding heel on one side and a screw on another side. The baseplate includes a complementary recess to receive the heel and a tapped hole to receive the fixing screw. The contact block may have similar tapped holes and recesses on its opposite end so that a second contact block may be mounted thereon.

Abstract: A control and/or indicator unit with screw terminals includes a one-piece body forming a flange provided with an external screwthread for fitting it by means of a nut to a support and surrounded at the rear by a cap in which are openings for wires and for access to the screws whose axes are parallel to the axis of symmetry of the body. The screws cooperate with connecting areas of bent conductive members held eccentric to the axis of symmetry in the body which provides a cylindrical internal housing open on the same side as the conductive members for at least one mobile contact plunger or a mobile contact plunger and a luminous component or a luminous component.
