Electric tool switch described in the utility model, wherein, metal-oxide-semiconductor is connected to speed-regulating control circuit plate left part, and installation cavity is positioned at the lower right corner place of base intracavity, and brace is plugged on the base of installation cavity bottom.
After adopting said structure, compared with prior art, the utility model has the following advantages: because the utility model electric tool switch also includes a brace, fly-wheel diode is button-shaped fly-wheel diode, brace is plugged on base, brace is provided with and presses down contact, cathode power supply input terminal is provided with pressure contact, be connected to pressure contact for fly-wheel diode and press down between contact, straight-through static contact is electrically connected with brace, and button-shaped fly-wheel diode not only own vol is small and exquisite, and there is not the power problem that more large volume is larger in the button-shaped fly-wheel diode of all size power requirements, their volume is all the same, therefore, people can select the button-shaped fly-wheel diode of different capacity specification to be arranged in the utility model electric tool switch according to actual needs, simultaneously, structure for the brace and upper pressure contact of fixing button-shaped fly-wheel diode in the utility model electric tool switch is equally very simply small and exquisite, therefore as from the foregoing, the utility model electric tool switch is on the basis ensureing compact conformation, not only can be adapted at small area analysis electric tool product uses, and can be adapted at large-current electric power driven tools product uses, thus considerably increase the scope of application of the utility model electric tool switch.
Because the base on the installation cavity top of the utility model electric tool switch is provided with guide vane end stop, guide vane end stop lower end and upper pressure contact upper end are close to, therefore under the support of guide vane end stop, upper pressure contact not easily produces Bending Deformation upwards, thus pressure contact is pressed on fly-wheel diode all the time well.
Because the left surface of the guide vane end stop right-hand member in the utility model electric tool switch and cathode power supply input terminal is close to, therefore when assembling, cathode power supply input terminal can follow grafting be fixed on base, can effectively avoid the middle part of cathode power supply input terminal to bend in assembling process the situation of deformation simultaneously.
Because the cathode power supply input terminal of the utility model electric tool switch is provided with bending, bending leans against guide vane end stop front end, bending one end is provided with the pin for being connected with speed-regulating control circuit plate, therefore guide vane end stop can produce effective support to this pin, thus when after this pin and speed-regulating control circuit plate, guide vane end stop effectively can support speed regulating control circuit board.
Due to the utility model electric tool switch to press down contact downward-sloping from front to back, press down contact rear end and brace junction curved, therefore make to press down contact and can produce elastic deformation after being connected with fly-wheel diode, thus enable to press down the contact thrust larger to fly-wheel diode generation, and then ensure that pressing down contact can be pressed on fly-wheel diode all the time well.
Because the contact front end that presses down of the utility model electric tool switch is provided with spacing lug, fly-wheel diode therefore effectively can be avoided in assembling process to press contact from above and press down the front portion in space between contact and to come off.
Metal-oxide-semiconductor due to the utility model electric tool switch is connected to speed-regulating control circuit plate left part, installation cavity is positioned at the lower right corner place of base intracavity, brace is plugged on the base of installation cavity bottom, therefore fly-wheel diode and metal-oxide-semiconductor distance is between the two made greatly to increase, thus greatly reduce the temperature impact of metal-oxide-semiconductor on environment residing for fly-wheel diode, and then effectively ensure that fly-wheel diode can all-the-time stable work.
