The fixed contact member 8 and the grounding fixed contact member 11 shown in FIG. 1 are basically cylindrical, and the number of fixed contacts 9, 10, 12, 13 is increased or decreased depending on the number of required circuits. In the example, since there are two circuits, there are two fixed contacts for each.
These fixed contacts are urged to be slidable in the direction of the movable contact member 3 by springs or the like built into each member. Next, the lead wires 14, 14 electrically connected to the fixed contacts 9, 10 by a method such as soldering or caulking are connected to a predetermined external circuit. The flange portion 15 of the fixed contact member 8 is fixed to the housing 1 with mounting screws 16.

ともできる。 Next, the flange portion 17 of the grounding fixed contact member 11 having the same structure as the fixed contact member 8 is fixed to the housing 1 with mounting screws 18 . The number of parts can be reduced by using the housing 1 itself as the bodies 8' and 11' of the fixed contact member 8 and the grounding fixed contact member 11.

完了する。 Next, the operation of the present invention will be explained. In FIG. 4, when the shift lever 21 of the lever unit 20 is operated, the detection switch in the lever unit detects its position and sends a signal to the central processing unit 22. The central processing unit inputs and judges other driving conditions 23, such as vehicle speed, loaded weight, throttle opening, etc., and adjusts the gear shift unit 24 based on the results.
The gears are changed by operating the solenoid valve built into the. At this time, the movable shaft 2 reciprocates in the direction A in FIG. 1, and at this time, the fixed contact and the movable contact come into contact with each other or separate. That is, in the position shown in FIG. 1, the fixed contact 9 of the fixed contact member 8 is connected to the movable contact 6 of the movable contact member 3 via the lead wire 14, which is a signal line from the central processing unit 22, and the grounding fixed contact member 11 is connected to the movable contact 6 of the movable contact member 3. from the fixed contact 12 of the body 1
1' Furthermore, it is electrically connected to the housing 1 to form a closed circuit, so the gear position at this time can be detected by this, and the rotation direction of the shaft 2 can be detected by using the switch of the present invention to detect the rotation direction. It is detected by providing it in a direction perpendicular to the shaft 2, for example, and sending it to the central processing unit 22.
If it matches the detection result of the shift operation, the shift operation is completed.

きるので接触がさらに確実となる。 In addition, in the embodiment, the movable contact member 3 is attached to the shaft 2.
Since the cylindrical portion of the movable contact member 3 is fitted into the movable contact member 3, a circuit is formed which is directly connected to the ground through the shaft 2, thereby making the contact even more reliable.

材をずらすことにより摩耗粉の害を極力減らすこ
とができる。 Furthermore, the arrangement of the fixed contact member 8 and the grounding fixed contact member 11 as shown in FIG. 3, which is a conventional example, is undesirable, and there is damage caused by abrasion powder at the contact portion. As shown in FIG. 2, the fixed contact member 8 moves to the left or right while avoiding the lower part, and the grounding fixed contact member 11 moves in the opposite direction to the fixed contact member 8. In other words, if the fixed contact member 8 is arranged at the 3 o'clock direction, the grounding fixed contact member 11 is arranged at the 10 o'clock or 11 o'clock direction. By shifting each fixed contact member in this direction, damage caused by abrasion powder can be reduced as much as possible.

移動又は回動は正確に検出することができる。 As described in detail above, according to the present invention, the transmission gear position, etc. can be reliably detected, and the durability of the electro-pneumatic operating device can be dramatically improved. Furthermore, as is clear from FIG. 1, etc., in the switch of the present invention, the shaft 2 not only moves in the A direction, but also rotates, so it is necessary to make accurate contact at any position. The movable contact is ring-shaped and is directly inserted into the shaft 2, and the fixed contact is mounted perpendicular to the axial direction of the shaft 2. With this configuration, movement or rotation of the shaft can be accurately detected.

Furthermore, by increasing or decreasing the position and number of the fixed contact members themselves, arbitrary positions can be detected.
