Radial type Tail Gate Switch and Wiper Device

The present invention relates to a tail gate switch, and more particularly, to a wiper device integrated with a tail gate switch of a rotatable radial type.

In general, a tact switch installs a circuit board with contacts in a direction perpendicular to the load pressing a button, and makes it come into contact with an elastic material cover with a conductive area formed on the inner surface to conduct current to the operation target. way of giving.

Therefore, the tact switch is applied to a vehicle to provide convenience in operation, and an example of this is a tact type tailgate switch applied to a tailgate of a vehicle. In particular, the tact-type tailgate switch is configured together with a rear wiper to provide convenience in mounting.

For example, the tact type tailgate switch configured together with the rear wiper provides the convenience of operating the tailgate locking device only by lightly pressing and releasing the tailgate switch disposed on the body side of the rear wiper shaft from the rear wiper side.
