Figure 10 shows an arrangement relationship between the movable contact plate 10-1, 10-2 ... 10-7 printed pattern _{P 1, P 2 ... P 8} , and the movable contact plate 10-1 are electrically connected to each other 10- 2, the printed patterns P ₁ and P _2, constitutes a switch for detecting that the output shaft 4 is operated to the right in FIG. 7 (OFF direction to release the door lock), also electrically connected to each other Movable contact plate 10-
3,10-4 and 10-5, and print patterns P ₃ , P ₄ and P ₅
Are switches for switching the direction of current supply to the motor 2, and the movable contact plates 10-6 and 10-7 which are electrically connected to each other.
And the print patterns P ₅ , P ₆ , P ₇ and P ₈ constitute a switch for causing the motor 2 to perform a brake operation.

The printed circuit board 8 has connector terminals 11a, 11b, 11c.
And 11d is mounted, which are connected to each of the extensions of the printed pattern P _1, P _2, P ₃ and P _8. In FIG. 7, D ₁ , D ₂ , D ₃ and D ₄ are diodes, which are connected as shown in FIG.
