"Multiple switches

The innovation relates to a multiple switch with a housing and a rocker mounted in it via pivot axes, which in their both pivoted end positions via contacts a first electrical conductor optionally connects to a second or third electrical conductor.

Such multiple switches are in various embodiments known. They are used, for example, as a remote control switch for slide projectors.

With the known switches of this type it is only possible to to connect the first conductor either to the second or to the third conductor.

The innovation is based on the task of creating a switch which, in addition to the known switching options, also allows a connection between the second and third conductor, in which case the contact with the first conductor should then be interrupted.

To solve this problem, the Initially mentioned type according to the innovation proposed that the pivot axes in guides of the housing transversely to the central position

the rocker are slidably mounted and a pressure element for actuating a central contact piece, which with is connected to the first conductor is provided.

It has proven to be useful that the guides through guide grooves and the pivot axes through on the rocker molded pins are formed.

Furthermore, it is proposed according to the innovation that the central contact is open to the first conductor when the end contacts are in contact with the common contact spring.

It has also proven to be useful that the pressure element. made of plastic.

A preferred embodiment of the innovation is described in detail below with reference to the drawing. Show it:

FIG. 5: a section along plane V-V according to FIG. 4.

A rocker 2 is mounted in the housing 1 so as to be pivotable about a horizontal pivot axis 2a. The horizontal pivot axis 2a becomes formed by pins 2a molded onto rocker 2. The pins 2a are rotatable and displaceable downward as shown in the drawing in lateral guide grooves 1a of the housing 1. Under

Two projections 2b and 2c are molded onto the end regions of the rocker. A pressure piece 3 is provided in the center of the rocker.

A contact spring 6 is connected to the first current conductor b via a contact piece 3a. Contact 4 is with the second Conductor a and the contact 5 connected to the third conductor c. When you press the rocker in the direction of the arrow 8, an electrical connection is established by means of the contact spring 6 from the first conductor b via the contact 5 to the second Conductor c made.

If you press the other end, a connection follows between the first conductor b via the contact spring 6 to the contact 4 and thus to the second conductor a.

In the center of the rocker is the pressure piece 3, which is made of plastic. This pressure piece 3 lies on the center contact and separates the center contact 3a from the contact spring 6, when the rocker is loaded in the center according to arrow 7 in FIG. There are then the second conductor a and the third conductor c connected to one another via the contact spring 6, while the first current conductor b is separated.
