Abstract

The invention relates to a switch having a switch housing, a number of module-type individual interrupter chambers which can be arranged in particular side by side in the switch housing and having at least two switching contact elements, and an actuating device which closes off the switch housing above the individual interrupter chambers. This actuating device serves to adjust a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber. The switching contact elements can be arranged in at least two different orientations in each individual interrupter chamber in an explosion-protected manner. Furthermore, in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements. This results in a switch with a simple adaptation option for housing installation or front-panel mounting, wherein all requirements for explosion protection are also fulfilled at the same time.

First claim

1 . A switch with a switch housing, a number of individual interrupter chambers arranged next to each other in the switch housing in a modular manner with at least two switching contact elements and with an actuating device closing off the housing above the individual switching chambers and provided for adjusting a cam element for the selective establishment of an electrical connection between the switching contact elements of an individual interrupter chamber, wherein the switching contact elements can be arranged in an explosion-proof manner in each individual switching chamber in at least two different orientations, and in particular the cam element of the actuating device can be arranged differently depending on the orientation of the switching contact elements.

2 . The switch according to claim 1 , wherein the individual interrupter chambers are one of covered and closed off via a common base plate connected to the switch housing, or each individual interrupter chamber has a base plate connected to the switch housing.

3 . (canceled)

4 . The switch according to claim 2 , wherein the connection between the switch housing and the base plate is made gas-tight.

5 . The switch according to claim 1 , wherein the actuating device has a rotary positioning drive which linearly adjusts the cam element, wherein the cam element has cams on an underside facing the switching contact elements for adjusting counter-contact elements between a contact position and a disconnected position.

6 . The switch according to claim 1 , wherein each individual interrupter chamber has a contact element cover connected to the individual interrupter chamber in accordance with the orientation of the switching contact elements.

7 . (canceled)

8 . (canceled)

9 . The switch according to claim 6 , wherein each contact element cover has a rounded supporting surface for a clamping screw of an associated switching contact element.

10 . The switch according to claim 6 , wherein each contact element cover has a lateral insertion opening for the arrangement of a plug-in identification plate.

11 . The switch according to claim 1 , further comprising a contact pin having an insertion end and a contact end opposite the insertion end, wherein the switching contact element has a receiving opening for the insertion end of the contact pin, the contact end being in contact with a counter-contact element in a contact position.

12 . The switch according to claim 11 , wherein a puncture-proof gap is formed between a gap cylinder of the contact pin and an edge of the receiving opening.

13 . The switch according to claim 12 , wherein a bearing groove for longitudinally fixing the contact pin is formed between the gap cylinder and the contact end.

14 . The switch according to claim 13 , wherein the base plate has two bearing clips projecting in the direction of the contact pin, which engage with free ends in the bearing groove.

15 . (canceled)

16 . (canceled)

17 . The switch according to claim 2 , wherein the base plate has a spring-receiving opening for a spring element which acts on a counter-contact element in a force-applying manner.

18 . The switch according to claim 1 , further comprising an auxiliary interrupter chamber arranged laterally on the switch housing and has at least two contact pairs.

19 . (canceled)

20 . (canceled)

21 . (canceled)

22 . The switch according to claim 18 , wherein the auxiliary interrupter chamber has on each side wall two switching contact elements with contact pins.

23 . The switch according to claim 18 , wherein the auxiliary interrupter chamber has a base plate with bearing clips, wherein each bearing clip has two U-shaped contact pin receptacles, and wherein at least one partition wall is formed between the bearing clips.

24 . (canceled)

25 . (canceled)

26 . The switch according to claim 23 , wherein side walls of the auxiliary interrupter chamber have retaining projections in the region of the switching contact element for holding clamping screws of the switching contact elements.

27 . (canceled)

28 . (canceled)

29 . (canceled)

30 . (canceled)

31 . The switch according to claim 1 , further comprising a coupling frame part configured to be arranged between two adjacent switch housings or between a switch housing and an auxiliary interrupter chamber, the coupling frame part having push-on arms and/or latching arms on both sides.

32 . (canceled)

33 . The switch according to claim 1 , further comprising a partition plate configured to be arranged between switch housings and/or between a switch housing ( 2 ) and an auxiliary interrupter chamber, wherein the partition plate has an open inner contour by means of which a connection can be established between switch housings and/or the switch housing and the auxiliary interrupter chamber.

34 . (canceled)

35 . The switch according to claim 1 , further comprising a latching device adjustably mounted on the switch housing.

36 . (canceled)

37 . (canceled)

38 . (canceled)

39 . (canceled)

40 . The switch according to claim 1 , wherein the switch housing has an upper opening and a lower opening through which a corresponding clamping screw is accessible from the outside.

41 . (canceled)
