Innovation is therefore based on the task of avoiding it this lack a bimetal snap holder that was initially

called type to develop, which has a "particularly small overall height has and is also characterized by a small number of τοη individual parts.

This object is achieved according to the hiring in that the bimetallic disk has an outer extension serving to hold the bimetallic disk in the housing and at the same time as a power supply, which is diametrically opposite the de gene contact, which is designed as a leaf spring.

In this way, with a very small number of individual parts, a very low overall height of the snap-action switch is achieved, which is very desirable in numerous applications.

In the drawing is an embodiment of the innovation illustrated schematically. The drawing shows a section through the bimetal snap switch in a perpendicular to the bimetal disc lying - ^ "bene.

The housing of the bimetal snap-action switch consists of a base plate 1, an insulation 2 arranged above it, a cover plate 3, an insulation 4 provided underneath, as well as other components that form the side walls of the use.

The two end walls consist of a bracket 5, with which a pin β is connected, as well as one over the pin 6 gripping pressure piece 7 to fix the electrical connections 8, 9

The connection 8 continues in a leaf spring 10 which forms the fixed contact. This contact is in the
