Electric power tool with a variable speed switch mounted thereto

摘要

A variable speed switch (30) includes a switch main body portion (33) which is accommodated in a housing (11) of an electric power tool (10) and mounted to the housing (11) so as to be capable of relative movement, and a load sensor (35) which is provided in the switch main body portion (33) and capable of outputting an electric signal in proportion to the amount of distortion caused by a pressing force. The switch operating portion (31) is mounted on the surface of the housing (11) so as to be capable of relative displacement with respect to the housing (11) and transmits a pressing force applied to the switch operating portion (31) to the load sensor (35), with the maximum displacement amount of the switch operating portion (31) being set to equal to or less than 5 mm.
