ABSTRACT:
A safety switch that includes a housing, a first switch, and a second switch. The switch has a two part rod that is axially moveable within the housing. The parts of the rod are co-operable with respect to one another and independently operable to activate one of the first and second switches. A biasing element is arranged to bias the rod parts into contact with a cam arrangement and arranged to bias the rod parts out of engagement with one of the respective switches. The cam arrangement is configured such that rotation of the cam arrangement will move the rod parts thereby activating the switches to allow the safety switch to conduct electricity.
