In this command and signal apparatus a cap (2) which comprises a shoulder carrying an annular diaphragm (3) at the side of the user appears through an opening of a cover plate (1). Displaceable arranged in the cap (2) is an acknowledgement element (4) with a hollow-cylindrical head part, a first guide, a second guide and a push rod. A sleeve (13) can be advanced, by way of a thread (12) extending at the circumference of a switch carrier (11), so far until this, together with the shoulder of the cap (2), forms a firm seat with the cover plate (1). Provided at the rearward end of the switch carrier (11) are board holders (14), which carry a second circuitboard (15) on which is arranged a microswitch (16) actuated by the pushrod. Arranged in the head part of the acknowledgement element (4) is an annular light conductor (18), which stands in connection with a first circuitboard (17) and which conducts the light from light-emitting semi-conductors integrated on the first circuitboard (17) to the underside of a glass pane closing off the command and signal apparatus at the front side. The light-emitting semiconductors are regulated by means of photo semiconductors in dependence on the ambient light, so that the light ring visible on the glass pane (19) lights up brighter the brighter the ambient light is. A flexible mufti-wire line (21) connects the first circuitboard (17) with the second circuitboard (15) by way of solder points (22) and plug contacts (23).
