Claims

[Scope of utility model registration request]

(1) In a printed board contact used in a switch or the like configured to short-circuit and open a fixed contact pair by a movable contact, the printed board contact forming the fixed contact pair is fixed at a predetermined position on the copper-clad laminate. A carbon paint film is formed to form a conductive path connecting the contact pair and the fixed contact pair, and the copper foil of the copper clad laminate is applied to the lower layer of the carbon paint film following the pattern of the carbon paint film. A printed board contact structure for use in a switch or the like, characterized in that the carbon paint film is formed so as to act as a contact surface with the movable contact.

(2) A printed board contact for use in a switch or the like according to claim 1 of the utility model registration claim, characterized in that the edge of the copper foil formed under the carbon paint film is plated. structure.
