"Electrical snap switch" Note: Inter Control., Inn .: W. Hollweck, Nuremberg

The DGBM relates to an electrical snap switch, with a Stationary, clamped, plate-shaped actuating arm, which has a middle * angled at the non-clamped end, from the clamping point has pioneering actuation tongue and with a snap-on, oppositely arranged leaf spring contact arm ,, whose pull arm is attached to the non-clamped end of the actuating arm and whose pressure arm end rests on the actuating tongue ^ and with fixed contacts on the non-clamped End of the contact arm.

Known switches of this type have a particular bi-metal strip to s whose movement is transmitted by a transmission device to the actuator arm, In these switches, the actuator arm is made of plain spring steel sheet.

These disadvantages are avoided in the electrical snap switches according to the innovation that according to the new proposal the actuator arm and tongue are made of bimetal.

The manufacture of the special bimetal strip and the transmission device., as well as their installation are therefore omitted with the snap switch according to the innovation. Furthermore, the Material for the manufacture of the actuating arm with its tongue.

In other types of snap-action switches, the actuator arm is also made of bimetal, but cranked and requires a special angle to support it. Also this one Compared to switches, the switch has the advantage of simpler and therefore cheaper production according to the innovation, as well as low potential for interference

According to further advantageous features of the innovation, the actuating arm and tongue are made from one piece and thereby the production is simplified considerably.

According to a further advantageous feature, the actuator is arranged in the region of the end of the tongue.

The innovation is explained in more detail below on the basis of an exemplary embodiment with the aid of schematic drawings. Show it:

Fig. 1 is a longitudinal section through a snap switch according to the innovation,

FIG. 2 shows a plan view of the object according to FIG. 1.

In Fig. 1, the plate-shaped actuating arm is 1 and the abgeii kelte tongue marked with 2. Both parts are made of one piece: -Bimetal manufactured.

4 is the leaf spring contact arm, the one with the tongue-shaped leaf spring 5 is also made in one piece. The free end of the leaf spring 5 engages in the recess j5 of the actuating tongue 2, where it is arranged laterally for the purpose of tension Shoulders.

At points 6 and J , the two parts 1 and 4 are welded together.

_{22 is a contact point 3} which is arranged at the free end of the contact arm and which alternately engages with the mating contact 19.
