Description

technical field

[0001] The invention relates to a trigger switch, in particular to a trigger switch for controlling a DC motor of a rechargeable electric tool. Background technique

[0002] Cordless electric tools control the rotational speed of a motor that drives a tip tool according to the pressing amount of the trigger. Such cordless electric tools are generally manufactured by incorporating a trigger switch that encapsulates a trigger and a control circuit of the motor.

[0003] As described in Patent Document 1, for example, a cordless electric tool has a motor on an upper portion of a grip that accommodates a trigger switch, and a battery on a lower portion. Therefore, at the lower end of the trigger switch there is a pair of power supply terminals for connecting the power supply, and at the upper part there is an output terminal for connecting the motor.

[0004] For example, as described in Patent Document 2, an insulating wall for isolating the two power terminals...
