One of the fixed and movable contact patterns is a coil-shaped contact pattern while the other of the fixed and movable contact patterns is a uniform surface pattern, at least one of the fixed and movable contact patterns has flexibility, and at least one of the fixed and movable contact patterns has a surface slanted from the center of the coil toward the outer peripheral edge of the coil. The coil-shaped contact pattern comprises first and second contact elements constituting a dual coil pattern.
