The invention relates to an actuator for a safety switch provided with at least one insertion slot with inclined insertion guides for the actuator, having a holder which can be fastened to a part whose open and closed positions are to be monitored, and which is fitted with the key mounted on it such that the said key can be moved, the key comprising a foot, and the holder being provided with a recess for the key on the side facing the key and with a bearing for the foot, the said bearing extending around the recess and allowing the foot to be displaced and rotated.

Actuator for a safety switch

A safety switch, operable by a removable coded actuator, is designed for mounting on a support surface in four different orientations. The switch has a substantially square cross-section and grooves or holes for receiving mounting fasteners extend across each side of the switch housing, the grooves being located in a common plane intermediate the ends of the housing.

Safety switch

A radius actuator for a safety switch of the type mounted to a hinged member, such as a flap, lid or the like, having a cover, a holder and a key. The key is pivotally mounted upon the holder such that the key may be rotated about an axis perpendicular to the plane of the pivoting circle of the radius actuator as the hinged member is opened or closed. The key being spring-biased into an insertion position and the pivot angle of the key being adjustable by means of a setscrew received by the holder. The holder being pivotally mounted relative to the cover such that the holder may be rotated about an axis within to a plane of the pivoting circle of the radius actuator as the hinged member is opened or closed. The holder being spring-biased into an insertion position and the pivot angle of the holder being adjustable by means of a setscrew received by the holder.
