Abstract

The present invention relates to a switch device. In particular, the present invention relates to a switch device that enables non-contact signal detection using a magnetic body and a sensor arranged to be positionally changeable. According to at least one embodiment of the present invention, a switch device is provided that enables non-contact signal detection by eliminating the possibility of signal failure caused by contact between parts in a conventional contact-type signaling method by using a magnetic body and a sensor arranged to change position. According to at least one of the embodiments of the present invention, the possibility of deterioration and damage between parts through repeated contact between parts can be prevented.

Description

Switch Device The present invention relates to a switch device. In particular, the present invention relates to a switch device that enables non-contact signal detection using a magnetic body and a sensor arranged to be positionally changeable. Conventional sunroof switch devices apply a contact-type switching structure to detect signal transmission. Specifically, conventional sunroof switch devices use a magnetic contactor contact method during sliding, and utilize rubber contacts during tilting and pushing. Conventionally, there was a problem in that repeated contact occurred between components through contact between a printed circuit board (PCB) equipped with a sensor and a counterpart during signal transmission, which could lead to deterioration and damage between components.
