Title:
変速スイッチ
Document Type and Number:
Japanese Patent JP5766843
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the displacement magnitude of a switch operation part relative to a switch body part thereby improving the attachment flexibility of a transmission switch and simplify the waterproof structure.SOLUTION: A transmission switch 30 according to the invention includes: a switch body part 33 which is stored in a housing 15 of an electric tool 10 and is attached so as not to move relative to the housing 15; and a load sensor 35 which is provided at the switch body part 33 and is formed so as to output an electric signal according to an amount of strain caused when the load sensor 35 receives a pressing force to be strained. A switch operation part 31 is attached to a surface of the housing 15 so as not to move relative to the housing 15 and transmits the pressing force applied to the switch operation part 31 to the load sensor 35. The maximum displacement amount of the switch operation part 31 is set to 5 mm or shorter.
