This low current input membrane switch is compatible with
microprocessor-based electrical/electronic systems and has the look and
feel of a conventional rocker switch.  

The Sigma Rocker comes complete with reliable LED backlighting and
provides an alarm and override feature for the Cole Hersee SureStart
48500 series of low-voltage disconnect switches.

Its silicone rubber actuator can be affordably customized by Cole
Hersee using laser etching technology. Options include custom colours,
imprint and graphics, and the shape and location of the LED lens.
