A two-step push-on switch in which the operating stroke of an upper movable contact is ensured, and particularly the width of the switch is reduced while the durability of the upper movable contact is improved, the number of parts is reduced, an the operation is improved. Dome-like movable contacts are placed in two or upper and lower stages in an invertible manner in a recess of an insulative body having a plurality of stationary contacts, and the upper movable contact is formed into an oval shape.
