Patent ID: 8653914

Claim:
A safety switch, comprising: a body, comprising: a contact block provided with at least two fixed contacts; a contact block plunger provided with a bridge contact, the contact block plunger being moveable to move the bridge contact into and out of electrical connection with the two fixed contacts; and a biasing element, arranged to bias the contact block plunger towards a control mechanism of the safety switch; a head containing at least a part of the control mechanism, engageable with an actuator that removably cooperates with the head and that is moveable to control movement of the contact block plunger upon engagement or withdrawal of the actuator, the control mechanism being moveable from a first configuration, where the actuator is withdrawn and the contact block plunger is in a position that keeps the fixed contacts and bridge contacts out of electrical connection with one another, to a second configuration, where the actuator is engaged and the contact block plunger is in a position that brings the bridge contact into electrical connection with, and bridges, the two fixed contacts; a magnetically operable switch located in the body; and a magnetisable material that is positionally fixed and extends from proximate to a. location of engagement of the actuator to a region proximate to the magnetically operated switch such that when an actuator comprising a magnet is engaged with at least a part of the control mechanism of the safety switch, the magnet is proximate the magnetisable material such that the magnetisable material is magnetised thus affecting an operating state of the magnetically operable switch.
