WIPO Patent Application WO/2017/138213

Kind Code:

A1

Abstract:

Provided are a control switch mechanism, a trigger switch, and a power tool, which are durable and resistant to vibrations, and may prevent a malfunction. The control switch mechanism (20) comprises an optical sensor (21) having a light-emitting element (21a) and a light-receiving element (21b), and a reflective plate (22) causing the amount of light received by the light-receiving element (21b) to be increased and decreased. The increase and decrease in the power tool output is controlled by accompanying the increase and decrease in the amount of light received by the light-receiving element (21b) due to the optical sensor (21) and the reflective plate (22) moving relatively to one another.
