A key holder designed for use with manual key switches affixes a key onto a control box. The key holder includes a rotor housing, a key rotor, and a threaded opening. The key is mounted into the key rotor before being inserted into the control box. Further, the key rotor is rotatably mounted into the rotor housing via the threaded opening. The key rotor includes an interior face, an exterior face, a threaded body, and a key slot. The interior face and exterior face are positioned opposite each other about the threaded body. The key slot traverses through the threaded body. To connect the key rotor to the rotor housing, the threaded body is screwed into the threaded opening. This transforms the rotational motion into the linear motion of the key rotor, which along with the locking feature of the manual key switch, prevents the key from rotating.

A safety switch (2) with a latching unit (12), by means of which an associated actuator (3) is held in a latched position. The latching unit (12) has an arrangement of latching jaws (14). Each latching jaw (14) is spring-mounted by means of a spring unit (15). The latching jaws (14) are concentrically arranged and each face one another with a first free end and delimit an insertion opening (A). The latching jaws (14) are held in latched position by the spring forces generated by the spring units (15). The latching jaws (14) can be displaced against the spring forces of the spring unit (15), which serves to enlarge the insertion opening (A).

Substrate processing systems and methods include selectively activatable remote computer access having lockout and/or tagout controls and/or features. Such substrate processing systems may include: (a) a first network switch including an input port and an output port; (b) a second network switch including an input/output port directly or indirectly connected with the first switch output port; (c) a lockable key switch provided in a power supply line and movable between OFF and ON positions; and (d) a key for moving the key switch between ON and OFF. When ON, an electrical circuit for supplying power to the first network switch and/or second network switch is completed, enabling remote computer control of the substrate processing system. When OFF, an electrical circuit for supplying power to the first network switch and/or second network switch is interrupted, thereby disabling remote computer control. The key can only be removed when in the OFF position.

An electric apparatus with safety connector for preventing electric shock, having an electric circuit comprising at least a pair of terminals electrically separated from each other, and a cover which covers the electric circuit so as to prevent access to it when it is disposed in the assembly configuration to cover the electric circuit. The cover is mechanically fixed in position by a plurality of attachment mechanisms. A safety connector associated with the cover and provided with an electric conductor element, wherein the security connector passes through the cover so as to short-circuit the terminals and a projection supports the electric conductor element and is movable from a closed configuration in which it short-circuits the terminals to an open position in which it does not short circuit the terminals. A cover element which, in closed configuration, at least partially overlaps at least one of attachment mechanisms.
