DE408128C - Push-button switch with a switch tongue mounted to pivot in the push-button - Google Patents

Description

(B 10565g

The invention relates to a push button switch of the known type, in which a in the push button pivotably arranged switching tongue, which slides on wedge surfaces, the Contact bridge moves. According to the invention, the return spring is the push button arranged so that it holds the switch tongues in the push button and also as a toggle spring for moving the contact bridge and as a locking spring in its end positions works.

An exemplary embodiment of the subject matter of the invention is illustrated in the drawing:

Ι Fig. And 2 show two vertical, mutually offset by 90 ⁰ cross sections, namely Fig. 1 after pressing of the push button with contact imaging power circuit bridge.

Fig. 3 shows the top view of the base with the circuit bridge and contacts and Connection screws of the line.

The reversing member b swinging out to both sides is held at one end by the helical spring c mounted in the hollow pushbutton α , which rests with a spreader d on the crosspiece of the circuit bridge /. The circuit ^{bridge / 7} swings about a metal axis g, which is mounted in the two carriers h which are insulated on the base. The two line connections i simultaneously form the contacts for the short circuit bridge / and are connected to one another when switched on and separated from one another and from the short circuit bridge f when switched off, as shown in Fig. 3. The fastening sockets k are used to fasten the switch cap .

The mode of action is as follows:

In the rest position, the spring c lies with its spreader d in an inclined position on the crosspiece of the circuit bridge f, whereas the laterally swinging changeover member b is held by the spring c so that it hangs vertically over the circuit bridge axis. When you press the push button it α lowers the changeover member b on the, short circuit bridge f, slides on its inclined edge until it engages in a notch at the foot of the inclined surface, and then pushes the short circuit bridge / from; their inclined position and at the same time the spring c from its inclined position beyond its central position. As a result, the spring c is tensioned even more and, after the dead center position has been exceeded, it tilts into the other inclined position, in that under the action of its released force it snaps the current-connecting bridge f into the other switching position. When releasing the push button α , it then pushes it back into its rest position, while even under its remaining voltage it remains pressing with its spreader d on the current connection bridge / and thus locks it in the switching position.

The next time you press the

button it α repeats the whole process to the other side, and it takes place the changeover of the current connection bridge / <in the other switching position, its blocking and the return of the push button a to its rest position.

In one switching position, the short circuit bridge / connects the two line connections i each other what they oppose this in

ίο the other switching position from each other and from disconnects and disconnects the line.

This push button switch can be adjusted by attaching a lever also use as a pull switch; the same can also be achieved by additional corresponding Design devices (e.g. step switch o. A.) To a series switch.

Claims (2)

Patent Claims: 1. Push-button switch with a switch tongue which is pivotably mounted in the push-button and which converts a short-circuit bridge, characterized in that the return spring (c) of the push- button holds the switch tongue (b) in the push-button and also by means of a spreader (d) as a toggle spring for moving the short-circuit bridge acts and locks them in their end positions. 2. Push-button switch according to claim 1, characterized in that the helical spring (c) holding the change-over element (b) holds it in the rest position perpendicularly above the axis of the current-connecting bridge.
