Abstract
Official abstract text for this publication.
An isolator switch assembly, especially an isolator switch and key assembly for a powered apparatus, such as a lawncare product, for example a lawnmower, includes a key, a keyway and an electrical switch positioned adjacent the keyway. The assembly is arranged to provide a first configuration in which the key is insertable into and removable from the keyway and the switch is open and a second configuration in which the key bears against an actuator surface of the switch to close the switch. In one embodiment, the assembly is arranged to provide a third configuration in which the switch is not actuated and the key is not removable from the keyway and is biased into a predetermined rotational position intermediate the first and second configurations. In a further embodiment, the assembly is provided with an over-torque or over-rotation prevention mechanism.
