PURPOSE: To prevent a circuit from being constituted in the case of erroneous operation for preventing malfunction by newly disposing a switch element in a switch unit, and connecting this between the power supply terminal side and another change-over switch.
CONSTITUTION: Switch elements in a first to a fifth switch units S1-S5 are operated for changing circuits between a power supply +B and a grounding terminal -E for controlling drive motors M1-M4, so a right and a left mirror surfaces LM, RM are actuated to be inclined right/left and up/down. In such a four- direction switch device SW, the second and the third switch units S2, S3 are provided with first switch elements 2-1a-2-1d, 3-1a-3-1d, and second switch elements 2-2a-2-2d, 3-2a-3-2d respectively.
