There is disclosed an actuation mechanism for actuating a power tool. T he actuation mechanism comprises a cable assembly comprising at least one outer cable (41) arranged coaxially around an inner cable (40), wherein the inner cable (40) is adapted to slide axially relative to the outer cable (41). The actuation mechanism also comprises at least one electrical contact (42) connected to t he cable assembly and a plurality of switch members (51, 54) connected to the cable assembly. In use, actuation of at least one predetermined one of the switch members causes the inner cable to move relative to the outer cable to close the electrical contact and actuate the power tool. By providing a coaxial cable assembly, having inner and outer cables connected to a plurality of switch members and arranged such that movement of the inner and outer cables relative to one another closes the electrical contact (42), this 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.
