いることを特徴とする密封型スイツチ。 A cylindrical casing that covers the tip of the lead wire,
a slide shaft disposed within the casing so as to be freely movable in the length direction thereof and whose tip protrudes outward from an opening at one end of the casing; and a movable contact provided at a proximal end side of the slide shaft. , a fixed contact disposed within the casing and electrically connected to the lead wire, and when the slide shaft is moved by a pressing operation, the movable contact moves integrally with the slide shaft. , in a sealed switch in which electrical on/off switching is performed between the movable contact and the fixed contact, a sealing member is interposed between the slide shaft and the casing at a portion protruding from the casing; The tip of the lead wire is covered with a protective tube that is adjacent to the casing and forms a space between it and the lead wire, and the protective tube is made of a flexible material and is opposite to the casing of the protective tube. The end of the protective tube is hermetically connected to the casing, and the other end of the protective tube is hermetically bonded to the outer periphery of the lead wire, and a sealed space formed within the protective tube and a sealed space formed within the casing are connected. A sealed switch characterized in that a sealed space and a sealed space are in communication with each other.
