<P>PROBLEM TO BE SOLVED: To provide a switch capable of providing a stable click feeling by suppressing variation in click feelings at eccentric pressing while using a movable contact-point made of an oval dome-like metal thin plate having a springy property that is deformable under pressing. <P>SOLUTION: A center fixed contact-point pattern 2 and a periphery fixed contact-point pattern 3 enclosing the former are formed on the upper surface of an insulating substrate 1. A movable contact-point 7 is placed on the periphery fixed contact-point pattern by striding over the center fixed contact-point pattern. On the center fixed contact-point pattern, a drawn-out part 4 is provided which, by avoiding a perpendicular bisector of a linear portions on both sides of the movable contact-point, passes any one lower side of the linear portions on both sides and then drawn out to the outer peripheral side of the movable contact-point from the center fixed contact-point pattern. On the periphery fixed contact-point pattern, a cut 3a is provided for drawing out to the outer peripheral side of the periphery fixed contact-point pattern through the drawing-out part. The drawn-out part is covered with an insulation body 9 to assure electrical insulation from the movable contact-point. <P>COPYRIGHT: (C)2013,JPO&INPIT |
