Multi-image lighted pushbutton switch with increased lens brightness
The SW44925 Series still matches industry requirements, including a rubber dust boot for panel protection and an enlarged ‘mushroom’ lens cap. The SW44925 now offers up to 8 total SMT LEDs to achieve 100fL brightness minimum and better light diffusion. Available in a variety of different lens cap, legend and filter materials, the unit is capable of display configurations in full, split, or quad segments, and can provide both continuously visible legends and hidden legends that become visible when LED circuits are activated. The SW44925 installs from the front of the panel and attaches via a mounting sleeve that retains the switch housing. With multiple LEDs built into the push button assembly, the product offers maximum brightness and redundancy. Night Vision (NVIS) filtering is also available. Switch action is available in momentary, momentary snap-feel, or alternate action.
Performance specifications for the SW44925 (from Series 644-2100) lighted pushbutton switches include life capability of 100,000 actuations minimum. Ratings are 2.0A resistive, 0.5A inductive, with an operating pressure of 1362g ± 454g and a plunger travel of 4.7mm. Switch contacts are silver plated (gold plating optional). Interconnect is provided with standard EMC solder lugs and accept 20AWG wiring (PC pin terminals are available).
