Claim:
1. A switch comprising: a rotary shaft adapted to rotate in response to an external force; a cam provided on the rotary shaft and including a cam action section, the cam being adapted to rotate in response to the rotation of the rotary shaft; a displacement member including a cam support section adapted to contact the cam action section, the displacement member being adapted to be displaced in response to the cam support section being pressed by the cam action section rotating; and a switch module for performing an on-off action in response to the displacement of the displacement member, wherein the cam action section is made of a sintered metal, wherein the cam support section is made of nylon containing a glass filler, wherein the nylon containing the glass filler is a resin softer than the cam action section, and wherein an amount of the glass filler is adjusted to fall within a range where (i) abrasion powder containing the glass filler does not cause abrasive wear on the cam support section, and (ii) the cam support section does not become deformed by a surface pressure during operation.
