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.
