In one illustrative embodiment, a power tool may comprise a housing supporting a motor, a primary switch coupled to the housing and configured to control a supply of energy to the motor, and an secondary switch that is reconfigurable between a first position near the primary switch and a second position spaced apart from the first position. When the secondary switch is coupled to the housing in the first position, the primary switch and the secondary switch may be configured such that a user holding the power tool with only one hand can operate both the primary switch and the secondary switch using the one hand. When the secondary switch is coupled to the housing in the second position, the primary switch and the secondary switch may be configured to require the user of the power tool to simultaneously operate the primary switch and the secondary switch using two hands.
