Abstract
A mode change switch for a power tool, which switch is moveable between at least two positions corresponding to different operating modes of the tool in which different components of the tool are brought into a meshing engagement. The switch comprises a manually operable driving member moveable between at least two positions in each of which it is adapted to be realizably restrained and a driven member which is adapted to be driven by the driving member between associated positions to directly or indirectly facilitate a change in operating mode. A spring engages between the driving member and driven member, to urge the driven member to follow the movement of the driving member. The switch is arranged so that a first end of the spring abuts a first pair of stop members and a second end of the spring abuts a second pair of stop members. One of each pair of stop members is located on the driving member. And the other of each pair is located on the driven member.
