PURPOSE:To reduce the cost of production as well as to improve the extent of working properties by a constitution connecting two self-holding reed switches for braking and stopping, two working magnets and two selector switches to one another. CONSTITUTION:A braking self-holding reed switch B and a stopping self-holding reed switch S both are tightly installed in one side body in the on-off direction of opening ends of a sliding door. In addition, two working magnets M2, M2 are set up in both opening and closing end sides of the sliding door in the shape of reversing their polarity. Furthermore two selector switches SW1, SW2 are installed there, and an interval between a controller C and both reed switches B, S are connected by the required wiring. Then, both these reed switches B, S are opening or closed by these working magnets M1, M2, and braking and stopping of the sliding door are carried out, while the sliding door is made to correspond to conversion from right-hand to left-hand and vice versa easily by inversion of both magnets M1, M2 and a changeover between both selector switches SW1, SW2. |
