L-Series
Switch
The L-Series rocker switch is an innovative product offering
total design flexibility, while at the same time setting new
standards for performance and reliability. Its versatile design
features include a neatly proportioned size that fits into an
industry standard mounting hole of 1.734 x .867 (44.0mm
x 22.0mm), countless unique choices for ratings, circuits,
colors, illuminations and laser etched legends. These single or
double pole switches also feature a broad choice of actuator
styles, colors, and lenses with up to twelve terminals offering
an extensive range of switch and lamp circuit options,
including LED or incandescent illumination. Additionally, an
optional plug-in terminal connector enables pre-wiring of
wire your harness.
