Claims

[Claims for Utility Model Registration] (1) The circuit board is attached to the circuit board with its lower surface in contact with the circuit surface of the circuit board, a recess is formed on the upper surface, and the bottom surface of the recess has a diameter smaller than that of the recess. A plate-shaped mounting member is provided with a through-hole that opens on the lower surface of the mounting member, and a presser portion that is housed in the recess and located at approximately the same level as the top surface of the mounting member is located within a radius from the base that is provided around the mounting member. a movable contact body in which a pressure receiving part is formed at the top of a leg-shaped intermediate elastic part extending upwardly and a contact member is attached to the lower surface of the pressure receiving part of the elastic body; a push button body whose upper part protrudes from the window of the case body which is in contact with the top surface and supported by the support body of the device and which is guided to be movable up and down within the window; A push button switch device comprising: a presser sheet member that presses a presser portion of a movable contact body; (2) The push-button switch device according to claim (1), wherein the mounting member is formed with a groove that communicates with the through hole and opens at the periphery of the mounting member.
