PURPOSE:To eliminate a rear wiper switch exclusively used for a rear wiper, by providing a wiper switch for commomly controlling both front and rear wiper driving motors to offer an operational relation therebetween. CONSTITUTION:A wiper switch 13 is set at LO mode to connect between BF and L. Accordingly, electrical current runs from a battery PS to the ground E1 through an ignition switch S, BF, the switch 13, L, and a front wiper motor MF, and therefore, the motor MF rotates at a low speed. Simultaneously, a contact 13A connects between G2 and CE, and therefore, a timing control circuit 15 for a rear wiper is also energized. The control circuit 15 drives a rear wiper motor MR through a relay RL2 in association with a cam switch signal from the front wiper side, at operating cycles less than that of the front wiper. Both wipers are similarly associated together in another mode. |
