ABSTRACT:
A rocker switch includes a drive member which is swingable about a fulcrum, a case supporting the fulcrum of the drive member, and an auxiliary switch. The drive member includes a main body, a push-section provided on the main body, a first stopper provided on the main body and positioned between the first push-section and the fulcrum, and a second stopper provided on the main body, the fulcrum being positioned between the first stopper and the second stopper. The case includes a supporter for supporting the fulcrum of the drive member, and first and second contact sections which the first and second stoppers contact non-simultaneously to each other according to a swinging motion of the drive member, respectively. The rocker switch further includes an urging section for urging the first and second stoppers to the first and second contact sections, respectively. The rocker switch generates a small noise when operating, thus providing quietness.
