The ELUM™ is a complete product family with a focus on flexibility. The ordering code is very straight forward and follows the traditional C&K nomenclature. All of the part numbers begin with ELUM. The switch function is next – OA indicates momentary, and EE indicates latching. The terminal style is indicated by TH for Right-Angle Thru-Hole and SA for Right-Angle Surface Mount. The contact material is indicated next by the letter Q for silver with gold flash followed by the illumination code and actuator style.
