<p><P>PROBLEM TO BE SOLVED: To provide a stop switch device which has simple constitution by suppressing the increase of the number of components and device weight. <P>SOLUTION: A stop switch device 1 includes a housing 2 which has a bearing hole 21, a shaft 3 which is inserted into the bearing hole 21, a knob 4 which is fixed to the shaft, and moves the shaft 3 to a second position when drawn out and to a first position when pressed in, and a stop switch 5 which is in an OFF state when the shaft 3 is at the first position and in an ON state when the shaft 3 is at the second position. The knob 4 is engaged with the shaft 3, and fixed to the shaft 3 when rotated in a predetermined direction. The knob 4 is released from the fixed state and can be disengaged from the shaft 3 by being rotated in the opposite direction from the predetermined direction in the state of fixation to the shaft 3 when the shaft 3 is at the first position. A cylindrical wall 22 is formed at a periphery of the bearing hole 21, and its height and interval with the shaft 3 are determined so that when the shaft 3 is at the first position, the shaft 3 cannot be drawn out with a finger. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
