We also supply 24V round rocker switches. Currently, the 12V switches are available in 13x19mm cutout, red or green illuminated or round, 20mm cutout, red or green illumination. Our 12V rocker switches use incandescent lamp illumination and we are able to source LED options. The LED switch will last longer which is something to consider if it is to remain on for long periods of time.Īt Alan Butcher Components, we stock a wide range of rocker switches, including 12V illuminated rocker switches.
