Abstract

PROBLEM TO BE SOLVED: To bring a cylinder peripheral end edge section into line contact with a fixed contact point center section, increase the contact area, and improve contact reliability by forming an upward protruded cylinder at a dome-like reversible contact point vertex section. SOLUTION: A dome-like reversible contact point 4 is made of a spring material, and an upward protruded cylinder 41 is formed at its vertex section 40. In the normal state that the contact point 4 is not depressed, a push button 5 is pushed up, the contact point 4 is kept in no contact with a fixed contact point 31, and a switch is opened. When the push button 5 is depressed, the contact point 4 is quickly inverted at the dead center while being deformation-depressed downward via a depression section 52, and the vertex section 40 is brought into contact with the fixed contact point 31. The cylinder 41 is formed at the vertex section 40 with its peripheral end edge section 43 located at the lower section, and the peripheral end edge section 43 is kept in contact with the center section 30 of the fixed contact point 31. The fixed contact point 31 and fixed contact points 32, 33 are connected via the contact point 4. When the contact point 4 is depressed via the depressing action of the push button 5, it is deformation-depressed downward, and it is quickly inverted to generate a click feeling when it passes through the dead center.
