Actuator-controlled keylock switch |
摘要 |
A key attached, for example, to the door of an electrical equipment cubicle is capable of sliding within a passageway so as to cause pivotal displacement of a cam and upward displacement of a push-rod, thus releasing a switch lug. A locking rod forming part of a slide-block which is coupled with the push-rod is capable of moving between a locking position in which an annular channel permits displacement of the key and an unlocking position in which the locking rod is engaged within a key notch. One end of the slide-block projects from the top face of the switching unit head in order to be downwardly displaced by an actuator, whereupon the key can be withdrawn without difficulty or danger.
