## Abstract

The present disclosure relates to a switch assembly for a motor vehicle component, including: an electronic basic body for arranging a contact member; an actuating member for actuating the contact member; a web associated with the actuating member, including a web portion with a web stop; a flexible switching mat having a basic portion for arranging the actuating member and the web; an operating member having an operating portion with an operating stop and an operating counter-stop disposed opposite to the web stop; a support member connected to the basic body or the switching mat having a support portion with a support counter-stop that contacts the operating stop in a non-actuated state of the switch assembly; wherein the web provided on the basic portion is arranged to be spaced apart from the actuating member provided on the basic portion, wherein the web encloses the actuating member at least partially.

## Claims

### Claim 1

A switch assembly for operating a motor vehicle component, comprising:
an electronic basic body, which is preferably configured as a circuit board for arranging at least one contact member, in particular a snap dome;
at least one actuating member for actuating the contact member;
at least one web associated with the actuating member and comprising a web portion with a web stop;
a switching mat formed from a flexible material with a basic portion for arranging the actuating member and the web;
an operating member, which has an operating portion with at least one operating stop and at least one operating counter-stop disposed opposite to the web stop of the web;
a support member connected to the electronic basic body or the switching mat and has a support portion with at least one support counter-stop that contacts the operating stop of the operating member in a non-actuated state of the switch assembly, characterized in that the web provided on the basic portion of the switching mat is arranged so as to be spaced apart from the actuating member provided on the basic portion of the switching mat, wherein the web encloses the actuating member at least partially.

### Claim 2 (depends on 1)

The switch assembly of to claim 1, wherein in the non-actuated state of the switch assembly, the actuating member remains in a substantially tension-free rest state and, at the same time, the web stop contacts the operating counter-stop in such a way that the web is elastically biased and the operating stop is pressed in the process against the support counter-stop.

### Claim 3 (depends on 1)

The switch assembly of claim 1, wherein in the actuated state of the switch assembly, the support counter-stop is disposed so as to be spaced from the operating stop and the bias of the web is increased in the process.

### Claim 4 (depends on 1)

The switch assembly of claim 1, wherein in the non-actuated state of the switch assembly, the actuating member rests against the operating member, or is spaced apart from it, in a tension-free manner.

### Claim 5 (depends on 1)

The switch assembly of claim 1, wherein the operating member comprises:
a venting duct adjoining the actuating member.

### Claim 6 (depends on 1)

The switch assembly of claim 1, wherein the support counter-stop or the operating stop are formed as an at least partially peripherally extending round projection.

### Claim 7 (depends on 1)

The switch assembly of claim 1, wherein the operating member is formed from a harder material than the switching mat.

### Claim 8 (depends on 1)

The switch assembly of claim 1, wherein the support member includes a guide channel for guiding the operating member.

### Claim 9 (depends on 1)

The switch assembly of claim 1, wherein the actuating member is configured as a lifting bellows, which has a jacket surface connected to the basic portion of the switching mat.

### Claim 10 (depends on 9)

The switch assembly of claim 9, wherein the lifting bellows is formed as a blunt and hollow cone, which has a cylindrical appendage.

### Claim 11 (depends on 1)

The switch assembly of claim 1, wherein the web is connected to the basic portion.

### Claim 12 (depends on 1)

The switch assembly of claim 1, wherein the web is disposed between the actuating member and the support member.

### Claim 13 (depends on 1)

The switch assembly of claim 1, wherein the web is formed to be tubular and the cylindrical appendage is disposed within the tubular web and concentrically therewith.

### Claim 14 (depends on 1)

The switch assembly of claim 1, wherein the actuating member has a tubular portion configured for actuating the snap dome of the contact member, wherein the tubular portion is disposed axially relative to the cylindrical appendage.
