Abstract

An electrical contact switch chamber is disclosed. The electrical contact switch chamber includes two contacts, a wall having a base and sides surrounding the two contacts, and at least one insulation slot having an opening extending transversely relative to a direction between the contacts. The at least one insulation slot is disposed along a portion of the wall between the two contacts.

First claim

What is claimed is:

1. An electrical contact switch chamber, comprising:
two contacts;
a wall having a base, a plurality of sides surrounding the two contacts, and a collection trough extending transversely between the two contacts; and
at least one insulation slot at least partially having a substantially U-shaped cross-section and having an opening extending transversely relative to a direction between the contacts and continuously from a first side, along the base, and to an opposite second side into portions of the base and the sides between the two contacts, the insulation slot at least partially expanding behind the opening which forms a tapered neck portion and having a portion extending parallel to the direction between the contacts.

2. The electrical contact switch chamber of claim 1 , wherein the collection trough is disposed between a contact and an insulation slot.

3. The electrical contact switch chamber of claim 2 , wherein an inner wall of the collection trough extends around a contact at a side closer to the contact.

4. The electrical contact switch chamber of claim 3 , wherein an edge of the collection trough has a chamfer at a side closer to a contact.

5. The electrical contact switch chamber of claim 1 , wherein a partition wall protruding from the base forms two part-chambers.

6. The electrical contact switch chamber of claim 5 , wherein the partition wall does not extend as far from the base as the sides.

7. The electrical contact switch chamber of claim 6 , wherein each part-chamber contains a contact.

8. The electrical contact switch chamber of claim 7 , wherein each part-chamber has an insulation slot.

9. The electrical contact switch chamber of claim 8 , wherein the insulation slots are separated from each other by the partition wall.

10. The electrical contact switch chamber of claim 1 , wherein each of the contacts has a contact plate and a base wider than the contact plate.

11. The electrical contact switch chamber of claim 10 , wherein each of the contacts further has a contraction disposed between the contact plate and the base, the contraction narrower than both the contact plate and the base.

12. The electrical contact switch chamber of claim 1 , further comprising two blow magnets opposite a contact and flex-conducting metal sheets connecting the blow magnets in a magnetically conductive manner.

13. The electrical contact switch chamber of claim 12 , further comprising a yoke of an electromagnetic linear drive, the yoke connected to a flux-conducting metal sheet in a magnetically conductive manner.

14. An electrical contact switch element, comprising:
an electrical contact switch chamber including
two contacts,
a wall having a base, a plurality of sides surrounding the two contacts, and a collection trough extending transversely between the two contacts, and
at least one insulation slot at least partially having a substantially U-shaped cross-section and having an opening extending transversely relative to a direction between the contacts and continuously from a first side, along the base, and to an opposite second side into portions of the base and the sides between the two contacts, the insulation slot at least partially expanding behind the opening which forms a tapered neck portion and having a portion extending parallel to the direction between the contacts; and

a bridging element having two contact counter-pieces.
