Description

Switch Device The present invention relates to a switch device. In a dial-type transmission of a vehicle, the rotation of the dial can be controlled by using a solenoid module that is intermittently coupled to the dial. In the conventional case, four solenoid modules operate individually to handle four shift modes (P, R, N, D). If the number of solenoid modules is reduced, improved durability of the transmission gears and cost reduction can be expected.
