Eled circuit configurations: each pushbutton cap contains 16 leds, 4 per quadrant, and all the electronics necessary for display illumination. The led circuit is either a single circuit with one common, g (style 1) or it is a horizontal split circuit with two commons, g and f (style 2). Each quadrant has its own i/o labeled a, b, c and d according to the quadrant it illuminates. Each quadrant has its own independent electronic circuit consisting of 4 leds and the driver, dimming and protection circuit (ddpc) needed for their operation. The led circuit can be either 28 vdc common anode (current sinking) or 28 vdc common cathode (current sourcing). Polarity is referenced with respect to commons g and f.
No other part numbers with same form, fit, and function found.
