Abstract
A membrane switch which can be opened and closed with a small pushing load. A fixed contact point 4 is formed on one surface of a first sheet 3. Flexible movable contact points 7 opposed to the fixed contact point 4 via a space in a manner movable to and way from the fixed contact point 4 are formed on one surface of a second sheet 6, opposed to the one surface of the first sheet 3. Insulators are arranged on the flexible movable contact points at locations except for the locations of push portions of the flexible movable contact points 7.
Claims4
