Integrated electronic switch

Abstract

The invention discloses an integrated electronic switch. The integrated electronic switch comprises a sealing cover, a mechanical system and a PCB component which are installed on a shell, wherein themechanical system is accommodated in a closed cavity formed by buckling the shell and the sealing cover, the PCB component comprises a first part accommodated in the closed cavity, and a second partaccommodated in the open cavity of the shell, a power switch assembly is arranged on the second part, the bottom of the shell is provided with a heat dissipation structure which can be directly or indirectly in thermal connection with the PCB component and the power switch assembly. The integrated electronic switch is advantaged in that heat generated by the PCB component and the power switch assembly is conducted out from the bottom of the shell through the heat dissipation structure, the heat dissipation effect on the PCB component and the power switch assembly is achieved, moreover, the internal space of the open cavity of the shell is not occupied, the bottom of the shell is wider, installation is convenient, the area of the heat dissipation structure can be large enough, and thereforethe heat dissipation effect on the PCB component and the power switch assembly is improved.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to an integrated electronic switch. Background technique [0002] The integrated electronic switch is a switch that integrates the mechanical part of the switch and the circuit control system to control the work of electric tools. Common electric tools include electric drills, electric grinders, electric wrenches, electric hammers, impact drills, and concrete vibrators. , electric planer, etc., through the integrated control switch, the motor start, stop and speed or steering adjustment of the electric tool can be realized. [0003] The existing integrated electronic switch mainly includes a housing, a mechanism casing, an operating mechanism, a contact mechanism, a circuit board, a control circuit, etc. The operating mechanism and the contact mechanism are installed in the installation space formed by the assembly of the casing and the mechanism casing. The circuit board ha...
