Claims

[Claims for Utility Model Registration] The switching knob 6 fitted and supported by the main body 1 can rotate within a predetermined angle range, and the rotation of the switching knob 6 is locked at both end positions of the angle, so that the contact point In a trigger switch that performs polarity switching by rotating the switching rotor 7 by a predetermined angle, a switch 1 is attached to the outer periphery of the circular body 6f that is integrated with the switching knob 6.
Or a plurality of protrusions 6c are provided, and the circular body 6f
The projection 6c is spaced apart from the projection 6c in the circumferential direction, and
A bottomed hole 6d in the radial direction is formed at a position closer to the switching knob 6, and a compression coil spring 6e is inserted therein.
The main body 1 is formed with a circular hole 1g that communicates with the rotor 7 storage chamber 1j and the outside, the circular hole 1g has a smaller diameter than the rotor storage chamber 1j, and a stepped portion 1k is formed in between. The inner diameter of the circular hole 1g is the same as that of the circular body 6f.
On the front surface of the circular hole 1g, two locking grooves 1h and 1h' into which the ball 6a is fitted are formed at a predetermined angular interval, and both grooves 1h and 1h' are It penetrates in a direction parallel to the axis of the circular body 6f, and is large enough to allow the projection 6c of the switching knob 6 to pass through, and the projection 6c of the circular body 6f of the switching knob 6 is inserted into the inner surface of the circular hole 1g. It is inserted into the grooves 1h and 1h' and rotated with the protrusion 6c exceeding the step 1k,
A trigger switch characterized in that the ball 6a is fitted into one of the grooves 1h and 1h'.
