An adapter (1, FIG. 1) is provided for the connection of an optoelectronic component such as an LED (light emitting diode) (2) to a circuit board (8) that lies in a case (34), wherein the adaptor positions the LED close to a window (32) in the top wall (30) of the case. The adapter has a pair of passages (4, 5) for holding conductors (11, 12) that connect terminals of the LED to SMD (surface mount device) contacts (6) that connect to the circuit board. The adapter holds the LED high enough above the circuit board, for the upper face (36) of the LED to lie in or close to the level of the window, so light from the LED can be readily seen from outside the case.

A mechanically operating pulse for generating electrical pulses dependent upon the rotation of direction of rotary shaft. The pulse generator includes a gear rim having internal toothing driven by the rotary shaft, a radially and generally deflectable switching sleeve which has a cam which engages in a tooth space of the gear rim. A spring member supports the switching sleeve on its side opposite the cam. Metal contacts are disposed adjacent to end areas of the spring member in such a way that said end areas are movable into contact with the metal contacts. A contact stud is disposed centrally of the spring member such that it mechanically retentions it in such a way that each end area is pressed against its adjacent metal contact and the cam is pressed into a tooth space of the gear rim. When the rotary shaft is rotated by one tooth, an end area of the spring member is moved into or out of contact with its adjacent member.

A pushbutton switch having a contact actuating member movable in the direction of actuation, and a restoring spring which is loaded when the actuating member is depressed. A laterally resiliently deflectable detent element engages an inclined cam surface on the actuating member. When the member is depressed, the cam surface moves downwardly over the detent element causing the element to be laterally deflected, thereby releasing the detent mechanism. Thereafter, the actuating member is then free to move on against the force of the restoring spring.
