SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/164215
Kind Code:
A1
Abstract:
Provided is a switch device which enables a decrease in the number of components and a reduction in the weight of a device as a whole without a decrease in communication distance.
The switch device is provided with: a switch unit that receives an operation for starting a vehicle accessory; a control substrate that performs control relating to wireless communication with a portable device; and a housing that houses the switch unit and the control substrate. The switch device performs wireless communication for authenticating the portable device via an antenna connected to the control substrate, and, upon the switch unit receiving an operation after authentication of the portable device, outputs a signal for starting the accessory. The antenna is provided with: a coil unit comprising a plurality of partially missing annular electrically conductive patterns coaxially formed on a circumferential surface of the housing; and a connection wiring unit connecting two open ends of each of the electrically conductive patterns to the control substrate.
