Abstract: A socket for a miniature incandescent lamp for the detachable and lockable insertion in a recess in a printed circuit board and for making electrical contact with the lamp by pressing the connecting leads against the printed circuit board with a separate manufacture of the socket and the lamp, the socket consisting of a hollow cylinder with two axially superimposed parts of different external diameters, the cylinder, to accommodate the connecting leads of the lamp, having two diametrically opposite longitudinal slots, the width of which corresponds approximately to the diameter of the connecting leads and which extend over the whole height of the part of smaller diameter and into the part of larger diameter by an amount corresponding at most to the diameter of the connecting leads.

Abstract: A holder for a small incandescent light bulb for the removable insertion in a plate opening, the holder being mounted mechanically and electrical contact with the contact areas of the plate being produced by two electrically conducting contacting parts that are connected to the light bulb connection wires, with the proviso that the electrically conducting contacting parts comprise an electrically conductive plastic, especially a polyester with embedded carbon fibers.
