Safety switch

A powered piece of equipment safety switch arranged to allow control of a supply of power to the equipment comprising:

• a body;
• at least one electrical component for controlling conduction of electricity by the safety switch;
• and
• a handle pivotably attached to the body and pivotable about a pivot point, the handle being pivotable between a first operating zone, a second operating zone, and a third operating zone, wherein:
• the first operating zone corresponds to a situation where the handle is not depressed and the electrical component is arranged, such that the safety switch cannot conduct electricity;
• the second operating zone corresponds to a situation where the handle is depressed to a first extent and the electrical component is arranged such that the safety switch is able to conduct electricity;
• and
• the third operating zone corresponds to the situation where the handle is depressed to a second extent and the electrical component is arranged such that the safety switch cannot conduct electricity,
• wherein the pivot point is moveable from a first position to a second position when the handle is depressed to the third operating zone, the second position of the pivot point being arranged such that the electrical component is arranged such that the safety switch cannot conduct electricity, irrespective of whether the handle is subsequently moved to the first or second operating zones.

A safety switch comprising:

• a body;
• at least one electrical component for controlling conduction of electricity by the safety switch;
• and
• a handle attached to the body and moveable between a first operating zone, a second operating zone and a third operating zone, wherein:
• the first operating zone corresponds to a situation where the handle is not depressed and the electrical component is arranged such that the safety switch cannot conduct electricity;
• the second operating zone corresponds to a situation where the handle is depressed to a first extent and the electrical component is arranged such that the safety switch is able to conduct electricity;
• and
• the third operating zone corresponds to the situation where the handle is depressed to a further, second extent, and the electrical component is arranged such that the safety switch cannot conduct electricity,
• wherein the safety switch further comprises a reset actuator which is arranged such that upon moving the handle to the third operating zone, the electrical component is maintained in an arrangement such that the safety switch cannot conduct electricity, until the reset actuator has been activated.

A safety switch comprising:

• a casing having an electrical contact assembly therein;
• a handle attached to the casing and pivotable about a movable pivot, the handle configured to manipulate the electrical contact assembly such that the electrical contact assembly is conductive when a first grip pressure is applied to the handle and the electrical contact assembly is non-conductive when no grip pressure is applied to the handle and when a grip pressure greater than the first grip pressure is applied to the handle;
• and,
• a reset actuator configured to move the pivot only in one direction.
