1. A push switch comprising:
a switch disposed on a seat;
a cylindrical case that accommodates the seat and the switch; and
a soft button comprising a side peripheral wall mounted on top of the case, and an upper operating wall; and
wherein the switch comprises a main portion, and an operating portion that projects up from the main portion;
wherein the upper operating wall comprises a pressing portion that presses the operating portion;
wherein the seat comprises a base formed from a hard resin, on which the switch is placed, a cover that is positioned around the main portion, and an upper wall that is positioned on the upper portion of the cover and covers the switch;
wherein the upper wall comprises a through-hole in a position corresponding to the operating portion, and a gap is disposed and provided in the interior of the upper operating wall;
wherein the operating portion and the pressing portion face through the through-hole; and

2. The push switch recited in claim 1 , wherein the main portion is cuboid having two first-side faces that face each other and two second-side faces that face each other; and
wherein the switch has two first-terminals drawn from one of the two first-side faces and two second-terminals drawn from another one of the two first-side faces;
wherein for each one terminal among said two first-terminals and said two second-terminals the cover is provided with a recess in a position corresponding to said one terminal, said recess following an embedding direction of the switch,
wherein a first-projection portion of the cover occurs between said two first-terminals and a second-projection portion of the cover occurs between said two second-terminals.
3. The push switch recited in claim 2 , wherein said cover is on contact with said two second-side faces.
