The invention provides a mouse switching device, and the device comprises a housing, an upper cover buckled on the housing, and a press part which is movably connected to the upper cover. The device also comprises a level structure which is rotatingly connected in the housing, a positive conductive disc, a negative conductive disc, a metal elastic piece disposed above the positive conductive disc and the negative conductive disc, a positive welding pin which is fixed below the housing and electrically connected with the positive conductive disc, and a negative welding pin which is electrically connected with the negative conductive disc, wherein the positive conductive disc and the negative conductive disc are fixed at the bottom of the housing. The metal elastic piece contacts with one of the positive conductive disc and the negative conductive disc. The press part cooperates with the level mechanism to press the metal elastic piece under the action of an external force, and enables the metal elastic piece to contact with the other one of the positive conductive disc and the negative conductive disc, so as to enable the positive conductive disc and the negative conductive disc to be connected. The device can prevent a user from repeatedly pressing the press part so as to prevent misoperation, can improve the hand feel for the user, and prolong the service life.
Description
technical field [0001] The invention relates to a switch device, in particular to a mouse switch device. Background technique [0002] At present, the mouse switch device usually includes a metal shrapnel and a pressing part. The pressing part presses the metal shrapnel under the action of an external force, and the metal shrapnel elastically deforms to conduct the circuit. During the pressing process, the stroke of the pressing part It is equal to the stroke of the metal shrapnel, but because the elastic stroke of the metal shrapnel usually has certain limitations, the user may not feel very obvious about the pressing stroke of the pressing part, thus causing the user to repeatedly press the pressing part, and repeated pressing will produce Repeated signals will cause certain troubles for user input. At the same time, the metal shrapnel in the current mouse switch device is square, and its own life is relatively short, which will also affect the life of the mouse switch de...
