Zusammenfassung:The utility model provides a small brush type structure impact acceleration switch. The small brush type structure impact acceleration switch comprises a housing; the movement assembly, the compression spring and the base assembly are sequentially installed in the shell and fixed in the shell in a buckling and riveting mode, and finally the bottom of the shell is sealed through sealing glue. According to the utility model, brush-type structure multi-point contact is adopted, so that the contact reliability is ensured; the internal structure adopts dual guidance, so that the mass movement assembly is prevented from deflecting in the impact process, and the switch is ensured to be recovered in place; over-travel is designed, that is, the switch can continue to move for a certain distance after a circuit is switched on, so that the contact reliability of the switch is ensured, and the switch body is prevented from being damaged under the condition of exceeding the specified impact value of the switch. 本实用新型提供了一种
