ABSTRACT:
A radius actuator for a safety switch includes a mounting, a spring-loaded operating key secured in the mounting and moveable between a slanted initiation position and a switch-actuating position. The operating key has a head assembly which is spring-mounted in a slider that is received in a recess of a locking wheel for to and fro movement. The locking wheel is rotatably supported in a mounting and has a cam so that a turning of the locking wheel causes the cam to move the slider in a direction of movement. The head assembly is supported outside the slide for tilting about a pivot axis in order to effect a slanted position of the operating key relative to the safety switch when turning the locking wheel.
