<p>The invention provides a key pad (6) for the on/off switch for a powered hand tool (2) in which the on/off switch is of the rocker type in which the switch mechanism is actuated by a rocker member (16) comprising two rocker components (18,20) pivoted about a pivot point (22) and is switched by applying pressure selectively to one of the two rocker components (18,20). The key pad (6) forms a sealed cover for the rocker switch (16) and is moulded from a resilient material, and comprises a pair of actuator pads (8,10), each of which actuator pads (8,10) is associated with a corresponding rocker component (18,20) of the rocker switch (16) and is moulded as a relatively thick pad section (8,10) linked to the key pad wall (12) by a relatively thin deformable circumferential linking section (14) and can be selectively switched between a first stable position and a selectively position in which the actuator pad (8,10) is depressed relative to the first stable position. <IMAGE></p> |
