Abstract:
1. A fixed contact pattern in which a conductive portion constituting a fixed contact is divided by a plurality of gaps, wherein the gaps include: an I-shaped gap that passes through the center of the fixed contact, and that has open ends, which are open towards both sides of the fixed contact, at both ends thereof, and L-shaped gaps formed by connecting longitudinal gaps that are located on both sides of the I-shaped gap and extend substantially parallel to the I-shaped gap, and lateral gaps that extend in a direction orthogonal to the longitudinal gaps, wherein the longitudinal gaps extend beyond a virtual straight line A-A that passes through the center of the fixed contact and extend in the direction orthogonal to the I-shaped gap, and are connected to the lateral gaps, and wherein the L-shaped gaps are arranged point-symmetrically about the center of the fixed contact.
