Pushbutton switch re-engineered to improve illumination brightness

The SW44925 Series is available in a variety of different lens cap, legend and filter materials, with display configurations available in full, split, or quad segments. The new series can provide both continuously visible legends and hidden legends which become visible when LED circuits are activated. End use application is ideal for flight cockpit or simulation, as specifications match industry standards.

The SW44925 installs from the front of the panel and attaches via a mounting sleeve that retains the switch housing, fitting into an industry-standard 0.698” square hole. The product offers maximum brightness and redundancy due to multiple LED’s built into the push button assembly. NVIS filtering is also available, whilst switch action is available in momentary, momentary snap-feel, or alternate action.
