Configurable switches are modular electromechanical switch systems that allow users to assemble a switch to suit their specific needs. The \\\"Contact Block\\\" components for such systems house the electrical contacts that make or break electrical contact, as well as the means by which those contacts are connected to the outside world. Available contact configurations are generally limited to single or double throw types, but are available in a variety of pole counts, normally open and closed configurations, and combinations thereof.

Choose a rocker switch by AC/DC ratings, contact arrangement, illumination, panel fit and sealing. Get practical checks for engineering and component sourcing.
