Electric switch

The invention relates to electrical switches, which consist of an elongated, flexible, electrically insulated housing and consist of a pair of elongated, flexible contact tongues which are held in the housing at a distance from one another. That The housing is compressible in order to bring the contact tongues into contact with one another at certain points.

The object of the invention is to provide a switch of the type mentioned, in which the housing is effected by locally compressing that the tongues touch each other at a plurality of spaced apart locations in order to increase thereby the Stromleit- or transporting capability of the switch.

According to the invention, this is the case with a switch of the type mentioned Type achieved in that the one tongue on its side adjacent to the other tongue with a pair of spaced apart, longitudinally extending ribs is provided, while the other tongue on its the first The adjacent side of the tongue has a large number of projections or

Has bulges which are spaced apart along the tongue, in such a way that each projection at a local, that is, compression of the housing taking place at one point touches each rib.

The invention is illustrated below with reference to the drawing illustrated embodiments explained in more detail. Figures 1 and 2 are sectional views of two embodiments of the electrical switch.

The switch shown in Figure 1 has a rural housing 1o in the form of a flexible tube made of rubber or another flexible, electrically insulating material, for example by extrusion. The housing has a flat bottom wall 1oa, a pair of side walls 1ob and a top wall 1oc. Each side wall is provided with a pair of internal grooves that run the length of the housing extend.

A pair of band-shaped or strip-shaped contact tongues 11 is fastened in the housing. The edges of these tongues sit in the grooves present in the side walls 1ob. The tongues 11, 12 are thereby held at a distance in the housing. The upper tongue 11 is provided on the side adjacent to the tongue 12 with a pair of ribs 11a extending in the longitudinal direction. The tongue 12 has a series of ^{bulges 12 a which are curved in the shape of a ball 1} and extend in the direction of the tongue 11.

If the housing is thus compressed at one point, one or more underlying protrusions 12a come about with both ribs 11a in contact.

In the embodiment shown in Figure 2 has the upper tongue 11 four extending in the longitudinal direction

Ribs 111a. The other tongue 112 has three rows of bulges 112a, which are offset from one another, so that there are even more points of contact when the housing is squeezed.

Claims (3)

Expectations 1 / Electrical switch with an elongated, flexible, electrically insulated housing and a pair of elongated, flexible contact tongues mounted in the housing, thereby characterized in that the one tongue C11) on the side adjacent to the other tongue (12) with a pair with Spacing of separate, longitudinally extending ribs (11a) is provided, and that the other tongue (12) on the side adjacent to the first tongue (11) several Has bulges (12a) which are distributed at a distance along the tongue and are arranged so that at a local Compression of the housing (1o) touches every bulge (12a) every rib (11a). 2. Electrical switch according to claim 1, characterized in that more than two extending in the longitudinal direction Ribs (111a) on one tongue (111) and several rows of bulges (112a) on the other tongue (112) are arranged. 3. Electrical switch according to claim 1 or 2, characterized in that that the bulges 012a, 12a) are part of a spherical shape. 309835 / 10η
