<P>PROBLEM TO BE SOLVED: To achieve cost reduction and improve contact reliability of a control switch. Ž<P>SOLUTION: A fixed contact 4 arranged on a bottom face inside a body 1a of a housing 1 has at least one protrusion 12 protruded toward a movable contact 3 side, on a face opposed to the movable contact 3 of a movable body 7. When the movable body 7 inside the housing 1 turns, and the movable contact 3 at an open state comes in contact with the fixed contact 4, the movable contact 3 is pressure welded to a tip of the protrusion 12. Accordingly, the fixed contact 4 with the protrusion 12 has a narrow contact area with a high surface pressure, thereby contact reliability is enhanced just as roughening by a shot blast process in the prior art. Moreover, the protrusion 12 can be formed by a press work, a knurling process or the like with lower cost than the shot blast process, thereby leading to cost reduction.
