The P26B-1D-BL is a single-pole momentary pushbutton switch from Carling Technologies' P26-Series, designed for shallow back panel applications with momentary-on circuitry. It features a 6A 125VAC and 3A 277VAC electrical rating with a slow-make, slow-break contact mechanism and medium actuation force of 13 oz typical. The switch incorporates a 1D bushing style with .465 inch length and .468 inch diameter, a .250 tab termination for quick-connect installation, and a black nylon button actuator. With 25,000 electrical cycles and 100,000 mechanical cycles rated life, plus 1000V dielectric strength (UL/CSA), it operates reliably across 0°C to 85°C. This switch is commonly used in intercoms, security systems, electronic signs, marine applications, and lighting control systems where momentary switching action is required.
