摘要： A barrier assembly includes an intermediate barrier member which is inserted from the front side of a mounting panel and a fixing barrier member which is inserted from the rear side of the panel and connected to the intermediate barrier member. After a plurality of small-sized controlling devices has been secured to the mounting panel, the intermediate barrier member is inserted into the area between each pair of adjacent controlling devices from the front side of the panel. Then, the fixing barrier member is inserted into this area from the rear side of the panel and connected to the intermediate barrier member. Thus, it is possible to prevent the intermediate barrier member from being pulled out forward of the panel and also from being withdrawn rearward of the panel by virture of the fitting engagement with the fixing barrier member. It is possible to remove the two barrier members toward the opposite directions, from which they are inserted when assembled, by disengaging them from each other.

摘要： A key switch which could, for example, be used to switch a power supply for a machine tool on and off, has a locking mechanism on a rotating element of a key disengages the locking mechanism on the rotating element. The key also engages the guide on the rotating element, thereby initiating the rotation of that element and activating the switching element. If an object other than the key is inserted, the lock on the rotating element will not be released, and the rotating element will be prevented from moving, so that the switching element cannot be activated. Furthermore in another embodiment, a machine stop detection signal is fed to an internal solenoid which prevents removal of the key until the machine stops completely.
