Abstract
A push button includes a button body, and a panel body. The button body includes a cylinder, a presser, and a rim. The cylinder has opposite ends, and an outer peripheral shape. The presser is disposed at one of the opposite ends of the cylinder, and forms a pressing surface. The rim protrudes beyond the outer peripheral shape of the cylinder, and has a rear surface facing the pressing surface back-to-back. The panel body includes a cylinder-shaped holder, a main body, and a flange. The cylinder-shaped holder holds the button body therein so as to enable the button body to reciprocate in an axial direction of the cylinder, and has an opening. The main body demarcates the opening of the cylinder-shaped holder. The flange protrudes radially inward, and has a leading end to be brought into contact with the rear surface of the rim.

A push button comprising:
- a button body comprising:
- a cylinder having opposite ends and an outer peripheral shape;
- a presser disposed at one of the opposite ends of the cylinder and forming a pressing surface;
- and a rim protruding beyond the outer peripheral shape of the cylinder and having a rear surface opposite the pressing surface;
- a panel body comprising:
- a cylinder-shaped holder holding the button body therein so as to enable the button body to reciprocate in an axial direction of the cylinder, the cylinder-shaped holder having an opening;
- a main body demarcating the opening of the cylinder-shaped holder;
- and a flange protruding radially inward and having a leading end to be brought into contact with the rear surface of the rim;
- and
- a circuit substrate equipped with a switch, the circuit substrate disposed apart from a rear surface of the panel body by a minor distance;
- and urging means disposed in the switch and urging the button body in a direction separating the button body from the circuit substrate, wherein
- one of the button body and the panel body further includes a tapered surface at a position where the cylinder and the cylinder-shaped holder face each other, the tapered surface being inclined with respect to an axial direction of the one of the button body and the panel body.
