PURPOSE: To obtain sufficient touch-feeling, surely prevent the fluctuation of circuit closing time, and carry out stable circuit closing operation by composing an elastic switch of a bowl like dome part, a pushing extrusion, a contacting part having a cylindrical side wall shape, and a movable contact point.

CONSTITUTION: An elastic switch consists of a bowl like dome part 11 which is deformed by pushing operation of an operator and a pushing extrusion 17 which is formed in the inner bottom of the dome 11 and pushed by a pushing operational part extruded in the lower plane of the operator. Also a contacting part 16 which is formed in the outer lower part of the dome 11 and maintains the distance between a movable contact point and a fixed contact point 7 until the pushing extrusion 17 is operated by the pushing operational part and a movable contact point which is extruded in the outer lower part of the dome 11 in the inside of contacting part 16 are installed. As a result, when a key is operated by pushing, the dome part 11 of a rubber switch 8 sags. Consequently, good touch-feeling is obtained due to the elastic resistance of the dome part 11 of the rubber switch 8 and the dispersion of circuit closing time is eliminated and stable circuit closing operation can be carried out.
