The invention relates to an old switch an essentially flat xta made of plate metal a light rotatable perpendicular to the surface of the plate metal Switching element, the canoe of which has a recess, into which an actuation pin is inserted can intervene. The actuation cam is generally attached to the shaft of a rotary resistor (potentiometerβ), which forms a structural uanzee with the switch, e.g. for switching a radio receiver on and off and for regulation the volume is used *

The switch shown in the figures is mounted on: an insulating base plate 1 on which a substantially flat switching element 5 stamped from resilient plate metal with a thickness of 0.1 mm, for example, is attached, which can be rotated about a short shaft 5. The surface of the plate details, from which the switching element is made, lies parallel to the base plate 1 and the shaft 5 is perpendicular to these two.In one of the edges of the switching element - which hand is circular in the illustrated case - is between two short cam-shaped lugs 7 and W 9 forms a recess 11 into which an actuating cam 13 can engage. This cam can be formed in the manner shown "on the inside of a shell-shaped actuating button rotatable about a shaft 15" using plastic, which also actuates a rotational resistance (not shown for the sake of clarity) that is operated in a manner known per se within the Button 17 on a plate 1 parallel base plate is attached.

Circular arc running narrow lugs 19 are provided, each of which is close to or (as shown) their free ends have a cam-shaped widened part 21. On the base plate 1 is a .pin-shaped?.? Stop 23 attached, the so between the ends of the narrow lugs 19 is arranged that with slight rotation of the switching element 3 of. the switched off position shown in Fig. 1 ago the cam shape raigen widened parts 21 below radially - in this case - from one another away - directed elastic bending of the lugs 19 over slide away the stop 23. After them the middle - thickest part of the cross section of the stop 23 have passed, the lugs 19 with the widened parts 21 spring towards each other again, whereby the sliding movement - actually accelerates a rotary movement will. Ίη of the switched-on position (Fig. 2), which then is reached, the free ends of the ^ lugs 19 are below radial Spring pressure on the side of a short attached to the plate 1 Contact pin 25, while the cam-shaped widened parts lie between the stop 23 and the contact 25. This is over the switching element 3 an electrical contact between the shaft 5 and the contact pin. 25, which can be used, for example, to switch on a electrical amplifier can be used, aeseen gain level can be regulated by turning the knob 17 forward. if the knob 17 is turned back again, the cam T 3 comes against the cam-shaped extension 7 to the plant and is the switching element brought back into the switched-off position shown in FIG.

From the above it follows without further ado that d & ss the switch described very little hardly used. This is true especially when the switch is on the back of the base plate a rotating resistor is attached; the required additional axial fluff then need not be more than 1 mti. A Another advantage is that the flat, only from to the surface parallel bending forces loaded switching element without bending can be punched or etched from a plate. This makes possible greater accuracy in manufacture than if, how, this burdened most of the forces parallel to the surface Switching elements is the case for setting the spring force or a permanent one, taking into account the space available Turn is required.
