The advantages of the one contact point remaining in contact on both sides can on these tongues leaking bridge contacts, no harmful contamination can occur on the spot, in this way regardless of the nature of the material, especially since it changes automatically due to a slight friction, or the dimensions of the contact sequence of the switching movement cleans. The bridging and, in the case of relatively low contact pressure forces, other contact points are electrically parallel and made fully usable. The disadvantages is switched, thereby achieving that in occasional known separate contact bridges with gemeinsachem failure of a contact point the current carrying mer Kontaktdruci spring si · u avoided

For resilient bridge bridges or the like actuated and by the contact clocks it is known to put this bridge contact loaded together for the purpose of increasing the compression spring 3. Contact security at each of the two interrupters This bridge contact, which consists of rigid or spring-loaded points can exist in at least two independent of the material and at its end the other resilient contact tongues to run out of usual contact pads or rivets 5 is in on (German utility model 1877 561).

Arranged contact plate through which the two bridge contacts are electrically connected to one another It has been found to be advantageous to only have one contact slug on the bridge contact 41 61 and two contact slugs 62, 63 on the other bridge contact 42, so on the one hand a clear abutment for the contact plate 7 is created and, on the other hand, the independent mobility Both bridge contacts 41, 42 is guaranteed. The contact plate 7 is provided with means for holding it and management of the bridge contacts with one another, e.g. B, angled tabs 71, 72, and for bracket the contact pressure spring3, e.g. embossing 73.
