Embodiment Construction

[0051] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0052] figure 1 as well as figure 2 A trigger switch 1 as one embodiment of the present invention is shown. The trigger switch 1 is incorporated into the handle of the cordless electric tool to control the rotational speed of a motor that drives a tool of the cordless electric tool.

[0053] The trigger switch 1 includes a frame body 2 made of insulating resin, and a user pushes it in with fingers (引き む) trigger 3, and has a pair of power supply terminals 4a, 4b connected to an external power supply, and a pair of output terminals 5a, 5b connected to an external motor. In order to dissipate heat, the switching element 6 is arranged outside the housing 2 and is connected to a circuit housed inside the housing 2 via insulated wires 7 , 8 , and 9 . In addition, the trigger switch 1 leads out a pair of lead wires 10, 11 from the housing 2, and can be connected to an ...

Abstract

A trigger switch performs speed control of a motor according to a pull-in amount of a trigger. A wiring path for lead wires connects the trigger switch and an auxiliary device. The wiring path is formed in an insulating wall. The insulating wall isolates a pair of power supply terminals, each connected to a power supply, from each other.

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...
