Abstract

A switch includes connection elements, connectable via a switching contact whose movable contact area is formed on a movable contact element which bears against the stationary contact area in the closed position. In order to achieve a design with improved positional accuracy, an embodiment of the invention proposes that the two connection elements and the movable contact element each have a planar flat side and all flat sides lie in a common plane. In an embodiment, the connection elements are arranged on one side of the common plane and the movable contact element is arranged on the other side; a subarea of the flat side of one connection element forms the stationary contact area; a subarea of the flat side of the other connection element forms a planar bearing area; and the movable contact element with its flat side bears movably against the bearing area.

First claim

The invention claimed is:

1. A switch, comprising:
connection elements connectable via a switching contact, the switching contact including a stationary and a movable flat contact area, the movable contact area being formed on a movable contact element movable, over a course of closing, from an open position into a closed position,
the stationary and movable flat contact areas each facing one another and being oriented parallel to one another, intersecting one another increasingly over the course of the closing process when viewed transversely with respect to the contact areas, and bearing against one another in the closed position,
the connection elements and the movable contact element each including a planar flat side and all of the flat sides lying in a common plane, the connection elements being arranged on one side of the common plane and the movable contact element being arranged on the other side,
a subarea of the flat side of one of the connection elements forming the stationary contact area and a subarea of the flat side of the other of the connection elements forming a planar bearing area, and
the movable contact element with its flat side bearing movably against the planar bearing area.

2. The switch of claim 1 , wherein supporting elements are arranged on a side of the movable contact element, the supporting elements including supporting areas which bear against the flat sides of the connection elements.

3. The switch of claim 2 , wherein the movable contact element is formed from a flat body, the movable contact area being arranged on one end of the movable contact element and the bearing area bearing against another end of the movable contact element.

4. The switch of claim 2 , wherein the movable contact element is in the form of a pivoting lever and is mounted pivotably.

5. The switch claim 2 , wherein the switch includes a housing shell and the supporting elements are integrally formed internally on the housing wall and the connection elements and the movable contact element are arranged in the housing shell.

6. The switch of claim 2 , wherein the two connection elements are plate-shaped and have the same thickness.

7. The switch of claim 2 , wherein the two connection elements have flat sides which are remote from one another on both sides and which run parallel to one another, wherein a further movable contact element with a flat side is opposite the movable contact element, wherein the two movable contact elements pivot in synchronism and the flat sides of the two movable contact elements face one another and are spaced apart from one another corresponding to the thickness of the connection elements so that they form a slot, which receives the connection element when the switching contact closes, and wherein the movable contact areas of the two contact elements make contact on both sides with stationary contact areas of the connection element.

8. The switch of claim 7 , wherein the two flat sides of the two movable contact elements each lie in a common plane with corresponding flat sides of the two connection elements, and wherein the two common planes are spaced apart from one another corresponding to the thickness of the connection elements.

9. The switch of claim 2 , wherein the two connection elements are each formed integrally from a flat material with the corresponding thickness by bending.

10. The switch of claim 1 , wherein the movable contact element is formed from a flat body, the movable contact area being arranged on one end of the movable contact element and the bearing area bearing against another end of the movable contact element.

11. The switch of claim 1 , wherein the movable contact element is in the form of a pivoting lever and is mounted pivotably.

12. The switch claim 1 , wherein the switch includes a housing shell and the supporting elements are integrally formed internally on the housing wall and the connection elements and the movable contact element are arranged in the housing shell.

13. The switch of claim 1 , wherein the two connection elements are plate-shaped and have the same thickness.

14. The switch of claim 1 , wherein the two connection elements have flat sides which are remote from one another on both sides and which run parallel to one another, wherein a further movable contact element with a flat side is opposite the movable contact element, wherein the two movable contact elements pivot in synchronism and the flat sides of the two movable contact elements face one another and are spaced apart from one another corresponding to the thickness of the connection elements so that they form a slot, which receives the connection element when the switching contact closes, and wherein the movable contact areas of the two contact elements make contact on both sides with stationary contact areas of the connection element.

15. The switch of claim 14 , wherein the two flat sides of the two movable contact elements each lie in a common plane with corresponding flat sides of the two connection elements, and wherein the two common planes are spaced apart from one another corresponding to the thickness of the connection elements.

16. The switch of claim 1 , wherein the two connection elements are each formed integrally from a flat material with the corresponding thickness by bending.

17. The switch of claim 1 , wherein the switch is a load interrupter switch.
