Switch

Abstract

A switch, especially a switch used for operating an electropneumatic parking brake of a motor vehicle, comprises a housing, an operation element held on the housing in a mode of being able to swing and a switch device provided with at least one electric switch element. The operation element can swing from a non-operation state to at least one operation state relative to the housing. The at least one switch element can be operated dependent on swinging of the operation element. The switch is provided with a reset device. The operation element can shift from the non-operation state to at least one operation state against the effect of the reset device. To provide the switch with a more compact and simpler structure, the operation element can be supported on the housing around a swing axis in a mode of being able to swing and being coupled with a swinging arm. The reset device is placed at a position, away from the swing axis for a certain distance, and applies a rest force in a mode of cooperating with the swinging arm. An accommodating chamber forms in the housing. A switch device is accommodated in the accommodating chamber. The reset device and the operation element are arranged on the opposite side surfaces of the switch device.

Description

technical field [0001] The invention relates to a switch, in particular for actuating an electric parking brake of a motor vehicle, comprising a housing, an operating element held pivotably on the housing and a switching device with at least one electric switching element, wherein the operating element Can be swung relative to the housing from a non-operating state to at least one operating state, and the at least one switch element can be operated in dependence on the swinging of the operating element, and wherein the switch has a reset device against which the operating The element transitions from a non-operative state to at least one operational state. Background technique [0002] This type of switch The switch used to operate the electric parking brake in a motor vehicle is a safety-related component that must be able to withstand a very high number of operations (typically 50,000 to 100,000) without being damaged, which is far from being damaged. Far more than the nu...

AI Technical Summary

Problems solved by technology

In order for the user to be able to perceive the switching process on the operating element tactilely, several components are also provided in conventional switches, with the result that conventional switches require relatively large installation space and have a complex structure

Conventional switches are also noisy due to the switching redundancy and large components required for their implementation, which is undesirable especially in advanced vehicles with electronic parking brakes
