The 2R177669GY is a 1 Pole BCD Complement thumbwheel switch with diodes provision, part of EECO's 1776 Series standard .500" wide switches. This switch provides 10 switching positions with binary-coded decimal complement output code, featuring a minimum life rating of 1,000,000 detents at 10 mA and 5 VDC at +25°C. The switch operates with a tangential operating force of 6-18 Oz. for the 1776 Series and supports a maximum switching load of 125 mA at 28 VDC or 115 VAC, with initial contact resistance of 100 mO maximum. The device is constructed with polycarbonate housing per Federal Spec LP-393A, corrosion-resistant metals, and gold over nickel plating on contacts, operating reliably across -20°C to +75°C. This switch is ideal for industrial control panels, test equipment, and instrumentation applications requiring precise decimal code selection with proven reliability and lead-free RoHS compliance.
