Abstract
A push-on switch includes a contact substrate provided thereon with a switch contact assembly, and an elastically deformable member disposed on the switch contact assembly. The push-on switch further includes a push button having a plate portion and a tubular portion. The tubular portion extends downward from the peripheral edge of the plate portion to surround an upper portion of the elastically deformable member. The plate portion is formed with a recess on an underside thereof at its center. A bottom surface of the recess is placed on a top surface of the elastically deformable member. The push-on switch further includes a tubular case fixed to the contact substrate. The tubular case supports the tubular portion of the push button so as to be vertically movable in the tubular case.
