The utility model discloses a waterproof travel switch, which comprises: an upper cover is installed on the lower seat, one side of the upper cover has a head cover, and there is a through hole between the upper cover and the head cover; a micro-switch is fixed in the upper cover through an epoxy resin layer; a trigger mechanism is installed in the head cover, and one end of the trigger pin passes through the through the through hole to face the micro-motion. The other end of the triggering pin is opposite to the triggering mechanism. The utility model solves the problem that the waterproof performance of the travel switch in the prior art does not meet the standard. The micro-switch is installed in the upper cover through epoxy resin seal, and the trigger mechanism is installed in the head cover. The micro-switch can be triggered by triggering the thimble through the head cover and the upper cover, and the channel triggering the movement of the thimble can be sealed through the rubber ring, thus greatly improving the waterproof and dust-proof performance. The utility model has the advantages of simple structure, fewer parts and convenient assembly. Excellent waterproof and dust-proof performance can meet the use requirements of various harsh environments.
