A switch is provided, which is stable in operating characteristics and can be operated with a small operating force, and which is long in life and easy to manufacture. The switch comprises a base, a moving contact piece having one end thereof, which is supported pivotally on the base, coming into pressure contact with a common stationary contact, an operating lever having one end thereof supported pivotally on the base and having a drive part, which extends from the one end, pushing a coil portion of the moving contact piece, and a cover fixed to the base to compress the coil portion. The operating lever pushes the coil portion of the moving contact piece whereby the moving contact piece turns about an end thereof, the coil portion slides on a bottom surface of the base, and the other end of the moving contact piece slides on a stationary contact exposed from an inner surface of the base.
A switch comprising a base, a moving contact piece made of a coil spring and having one end thereof, which is supported pivotally on the base, coming into pressure contact with a common stationary contact, an operating lever having one end thereof supported pivotally on the base and having a drive part, which extends from the one end, pushing a coil portion of the moving contact piece, and a cover having a planar shape capable of covering the base and fixed to the base to compress the coil portion, and
