Abstract
A push button which is employed in a control panel includes button body, a pushing finger, and a core. The button body has hollow space formed at an inner portion thereof and a bellows portion formed around a side portion thereof. The pushing finger protrudes upwardly from an outer surface of an upper end portion of the button body for receiving a pushing force. The core is retained in the hollow space, and fixed at an inner surface of the closed upper end portion. When the bellows portion of the button body is elastically compressed by a pushing force, an other end portion of the core is protruded from the lower end portion of the button body, and when the pushing force is removed from the pushing finger, the other end portion of the core is retained in the hollow space.
