Description

Technical Field

[0001] This utility model relates to the field of power tool switch technology, specifically a multi-contact power tool switch. Background Technology

[0002] A tool switch, also known as a power tool switch, is a specialized switching device that integrates intelligent control functions for power tools. It is compatible with both AC and DC operating environments and can be used in power tools such as electric drills, hammer drills, and cutting machines. The core functions of this device include speed control, current regulation, and soft-start protection. It comes in various types, including speed controllers, trigger switches, and rocker switches.

[0003] The switches used in existing power tools for control and signal transmission generally have only three contacts on the switch frame during actual use and improvement. However, some applications require additional switch contacts to meet the need for additional control or signal circuits. Since existing power tools only have a single control circuit inside, the power tool cannot be used when the control circuit inside the power tool fails, requiring the user to disassemble and repair the power tool, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a multi-contact power tool switch to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-contact power tool switch, comprising a housing: both ends of the housing are provided with retaining plates; a button cap is rotatably disposed at the middle position of the top of the housing; retaining grooves are opened at the middle positions of both sides of the button cap; retaining members are slidably disposed at the middle positions of both sides of the top of the housing; magnetic suction members are rotatably disposed at both ends of the bottom of the button cap; suction members are provided at both ends of the interior of the housing; pressing members are provided at both ends of the bottom of the button cap; a first moving contact and a second moving contact are respectively disposed at both ends of the bottom of the housing; a first normally closed contact and a second normally closed contact are respectively disposed at the end of the bottom of the housing near the first and second moving contacts; and a normally open contact is disposed at the middle position of the bottom of the housing.

[0006] By adopting the above technical solution, two sets of moving contacts and normally closed contacts are provided on the housing. Therefore, the switch can control two sets of control circuits and signal transmission on the power tool. When the button cap is tilted in different directions, the pressing parts in different directions can press the rocker conductive parts in different positions, so that different control circuits in the power tool can be controlled by the switch. Even if the circuit in the power tool fails, the power tool can still be used.

The fixing component and the rotating component are rotatably connected on the magnetic suction component. Fixing components are provided at both ends of the bottom of the button cap, and a magnet is provided at the bottom of the rotating component on the magnetic suction component.

The extrusion head is provided at the bottom of the buffer member on the extrusion member, and the extrusion head on the extrusion member abuts against the top of the rocker conductive member.
