The 5501MBLKREDGRN is a dual-color LED illuminated pushbutton switch featuring integrated red and green LEDs with a black cap and SPDT (Single Pole Double Throw) circuit configuration. The switch is rated for 12 mA at 24 VDC and incorporates fixed and moving contacts made of copper alloy with gold plating, providing a contact resistance of 50 MO maximum and insulating resistance of 100 MO. Key operational characteristics include an operating travel of 2.5 mm ± 0.5 mm, operating force of 170 ± 50 grams, operating temperature range of -10°C to 60°C, and a minimum operating life of 500,000 cycles. The red LED has a peak emission wavelength of 695 nm with luminous intensity of 2.2 mcd typical, while the green LED operates at 570 nm with 15.0 mcd typical intensity. This switch is ideal for industrial control panels, machinery interfaces, and applications requiring visual feedback with dual-color indication.
