ABSTRACT:
An actuation mechanism for actuating a power tool that includes a cable assembly comprising at least one outer sheath (41) arranged coaxially around an inner cable (40), wherein the inner cable (40) slides relative to the outer sheath (41). The actuation mechanism also comprises an electrical contact (42) connected to the cable assembly and a plurality of switch members (51, 54) connected to the cable assembly. The coaxial cable assembly provides the advantage that a power tool with a two handed dual-switching mechanism can be actuated without the need for two independent electrical contacts wired in series, thereby reducing the amount of electrical wiring and components needed. Additionally, an electrical contact is provided with a connecting structure connected to the handle assembly and to the housing and adapted to enable actuation of the tool in a plurality of orientations of the handle assembly relative to the housing.
