摘要： A capacitance type push-button switch which includes a movable member carried by the lower end of a key stem and including a holding member made of an elastic material of high compressibility and having a convex lower surface, a movable electrode made of an electrically conductive and flexible material held to the lower surface of the holding member, a dielectric film carried by the movable electrode and comprised of a synthetic resin of a fluoride type which can be brought into contact with two stationary electrodes to vary the capacitance therebetween, means including a pair of suspending pieces each carrying at their lower end portions a respective pawl adapted to engage the holding member when it is raised to its upper position for holding it in place, and means for releasing the pawls to bring the dielectric film into pressed contact with the stationary electrodes.

摘要： A novel capacitance type switch has a completely dust proof structure and ensures smooth switch operation. The switch comprises a stem supporting a movable contact and slidably inserted into a switch case; a plurality of holes formed in the switch case around the stem so as to permit air to pass therethrough into and out from the switch case; a cover surrounding the holes and in intimate contact with the switch case so that the inside of the switch case can communicate with the inside of the cover; the cover being made of a resilient material; and a dust filter made of a seal material interposed between the inside of the switch case and the atmosphere.
