Claims

[Scope of Claim for Utility Model Registration] In a two-stage push button device having an escutcheon in which push button members are arranged in two upper and lower stages, and a main board disposed approximately at right angles to the escutcheon, the main board includes: A push switch is provided so as to be activated by being pressed in a direction perpendicular to the main board, and a switch operating member is also disposed on the main board in front of the push switch. The push button member is provided with an operating part whose other end presses the push button in a substantially vertical direction, and a hinge part which serves as a fulcrum for the rotation of this action part. A rotation shaft is provided as a rotation fulcrum for the switch, and an operating rod is also provided on the lower side of the back side of the switch to press one end of the operating part of the switch operating member when the switch is rotated. A rotation shaft serving as a rotation fulcrum for the escutcheon is provided on the lower side, and an operating rod is provided protruding from the upper side of the back surface to press one end of the operating portion of the switch operating member during rotation. A two-stage push button device.
