摘要： A switch mechanism for use in for example a rope switch. The mechanism comprises a switch which is actuable to switch between first and second conditions, for example to turn on and off kinetic machinery. A cam follower actuates the switch, the cam follower bearing against the surface of a rotatably mounted cam. An actuator member is displaceable relative the cam and a linkage is provided between the actuator member and the cam such that displacement of the actuator member from a predetermined position causes the cam to rotate and actuate the switch. The linkage comprises a lever mounted on a pivot that is displaced with the actuator member, the lever co-operating with a surface of a stationary cam such that displacement of the actuator member causes the lever to pivot and rotate the rotatable cam.
