MR-21 On-Off Rocker Switches

These SPST and DPST switches snap-fit securely into an international standard size panel cutout 19x13-mm, and allow for close adjacent mounting with their 21x15-mm bezel side.  These rocker switches feature a black bezel (other color are also available) and several optional actuator color choices.  The judicious location of the lens on the lighted models enables easy viewing from either the front or side.  The lighted models are available with either a 120 or 240VAC neon lamp or 12VDC incandescent lamp for automotive application.
