| A contact spring is provided to prevent erroneous contacts caused due to tiny dusts and to decrease characteristic variation after repeated operations. A switch(2) contacts or moves away a mobile contact point(4) inside a dome-shaped click-enabled mobile contact spring(3) with respect to a corresponding fixed contact point. The mobile contact point(4) and the fixed contact point are electrically connected or disconnected with each other via the switch(2). A thickness less than two thirds of the mobile contact spring(3) is protruded by an inward half-cutting process at plural positions. The positions have identical central angles with respect to the center of a circle on a circumference with a center at the center of the mobile contact spring(3).
