Featured in the same design format as the series 644-2100, units can accommodate up to four T-1 (3 mm) sub midget flange based LEDs (model SW44267). For greater display design opportunities, the units feature interchangeable lenses with a clear or smoke grey top cover, black opaque sides, and legend filters. Legends up to 0.125 in. high can be provided, with black characters or hidden legend displays. Multi-function units are capable of display configurations in split, quadrant or full segments, and can be provided in both continuous visible legends and hidden legends that become visible when switch functions are activated.

Series SW44267 models are 0.75 in. square and can be snapped in from the front of the panel, mounting into a standard 0.698 in. square hole. A back-up bracket affixes to the rear of the panel, secured in by a threaded locking arm. Momentary styles require only 1.6 in. behind panels, while Multi-Function units may require up to 3 in., depending on internal circuitry. Interconnection to circuitry or wiring is provided by standard solder lug terminals, which accepts 20 AWG wire (standard), or the unit can be provided with PCB pin terminals or wire harness. The series SW44267 is rated at 30 Vdc (115 Vac), 2 A resistive, 0.5 A inductive. Other features include operating pressure 16 oz (±4 oz) (Momentary) or 32 oz (±8 oz) (Alternate Action). Switch life is rated at 100,000 minimum actuations. The unit is rated to IP64.
