A switch mechanism for a power tool switchable between an ON and OFF state including a support structure; a first actuator rotatably mounted on the support structure and which is rotatable between a first position and a second position, wherein the first actuator is capable of being releasably latched in either of the first or second positions. The first actuator includes a recess. A second actuator is a slidable button located inside of the recess of the first actuator so that the first actuator at least partially surrounds the second actuator, and is linearly slidable within the recess between a first position and a second position. The second actuator is biased towards its first position. Movement of the first actuator from its first position to its second position, when the second actuator is in its first position, switches the switching mechanism to its ON state; and movement of the first actuator from its second position to its first position, when the second actuator is in its first position, switches the switching mechanism to its OFF state. Movement of the second actuator from its first position to its second position, when the first actuator is latched in its second position, switches the switch mechanism to its OFF state.
