Abstract

The invention provides a switch device and an electric tool with the same. The switch device comprises a circuit board, an MOS tube connected with the circuit board and comprising a radiating body andan electrode D connected with the radiating body, an electrode D connecting structure, wherein the radiating body is electrically connected with the electrode D of the MOS tube, and the electrode D connecting structure is connected with the radiating body and the circuit board so as to connect the electrode D of the MOS tube with the circuit board. The problem can be solved that a switch device in the prior art is complex in structure, complex in assembly process and high in cost.

Description

technical field [0001] The invention relates to the field of tools, in particular to a switch device and an electric tool with the same. Background technique [0002] Currently, there are two commonly used brushless switch devices for electric tools on the market, one is a separate switch device and the other is an integrated switch device. For the separate switchgear, the control module of the motor is arranged outside the switchgear, which is cumbersome to install and the installation efficiency is low, while the control module of the motor is set inside the switchgear for the integrated switchgear. Although the integrated switch device can solve the problem of low installation efficiency, due to the limited installation space, an additional heat sink is required to dissipate heat from the MOS tube, resulting in a complex structure of the switch device, complicated assembly process, and high cost. Contents of the invention [0003] The main purpose of the present invent...
