Safety holder
First Claim
1. An assembly having a safety switch and a safety holder for preventing insertion of an actuator into said safety switch, comprising:
- said safety switch including a switch body having a box-shaped body and actuator insertion openings provided in two different surfaces thereof through which the actuator is insertable, and a contacting portion provided within the switch body, connection of which is switched in response to the insertion of the actuator,said safety holder including;
a base body that engages with one of the actuator insertion openings provided in the two different surfaces and blocks the one of the actuator insertion openings; and
a slide body movably attached to the base body so as to be able to block, when the base body is engaged with the one of the actuator insertion openings, the other one of the actuator insertion openings provided in the two different surfaces by engaging with the other actuator insertion opening.

Abstract
A safety holder is provided that firmly attaches to a safety switch so that safety of a worker is enhanced. The safety holder includes a base body 21 that is inserted into an actuator insertion opening 7, and limits rotation of a drive cam 9 by engaging at a tip end portion (hanging portion 21C) thereof with a concave portion of the drive cam 9 of the safety switch, and a slide body that is movably attached to the base body 21 so as to be insertable into an actuator insertion opening 8 with the base body 21 inserted in the actuator insertion opening 7, and when the slide body is inserted into the actuator insertion opening 8, that enters and engages with an engagement hole 36 of the base body 21 whose tip end portion (insertion arm 34) is being inserted into the insertion opening 7.
