Abstract
A safety switch with a contactor structure including first and second contactor contacts electrically connected to each other. The switch has an 'on' state in which first and second terminal contacts are contacted with the first and second contactor contacts, respectively, to thereby electrically connect the terminal contacts therebetween, and an 'off' state in which the terminal contacts are not electrically connected to each other by the contactor structure, whereby current cannot flow between the terminal contacts. The switch also has a cycle control mechanism with a normal-state in which the switch is free to cycle between the 'on' and 'off' states, and a welded-state in which one of the terminal contacts is welded to one of the contactor contacts and the other of the contactor contacts is separated from the other of the terminal contacts. When the cycle control mechanism is in the welded state, the switch is prevented from moving from the 'off' state to the 'on' state.
