Abstract
A safety switch device for monitoring the position of a protective cover, the cover being pivotable about an axis into and out of a closed position. The safety switch device includes a fixed position switch unit which houses at least a first electrical signal generator which will be switched between states in response to movement of the protective cover from the closed position, the signal generator being operated by an actuator which rotates about an axis. The switch device also includes a fastener element which is adjustably mountable to the protective cover and an articulated mechanical coupling which extends between the fastener element and the signal generator actuator, the coupling element being movable in at least two planes.
