Micro-stroke button switch

The utility model relates to a micro-stroke button switch which is characterized in that the micro-stroke button switch comprises an outer shell, two sides of the outer shell are provided with a pressing part and a sealing part, an inner cavity is formed between the pressing part and the sealing part, and a circuit board and a conduction piece are arranged in the inner cavity. A first contact block in contact with the pressing part and a second contact block in contact with the circuit board are arranged on the two sides of the conduction piece, a third contact block in contact conduction with the second contact block is formed on the circuit board, and the conduction piece is made of an elastic silica gel material. According to the utility model, the conduction member made of the silica gel material has good elasticity and can be deformed after being pressed so as to be in contact with the third contact block on the circuit board to realize conduction, and then the silica gel material can be self-reset.
