In one illustrative embodiment, a power tool(10) may comprise a housing (14) supporting a motor (16), a primary switch (12) coupled to the housing (14) and configured to control a supply of energy to the motor (16), and a secondary switch (20) that is reconfigurable between a first position near the primary switch (12) and a second position spaced apart from the first position. When the secondary switch (20) is coupled to the housing (14) in the first position, the primary switch (12) and the secondary switch (20) may be configured such that a user holding the power tool (10) with only one hand can operate both the primary switch (12) and the secondary switch (20) using the one hand. When the secondary switch (20) is coupled to the housing (14) in the second position, the primary switch (12) and the secondary switch (20) may be configured to require the user of the power tool (10) to simultaneously operate the primary switch (12) and the secondary switch (20) using two hands. |
