The Senco 2E21025TB Pressure Switch is a genuine OEM replacement that governs when a Senco air compressor starts and stops, enabling reliable, automatic cycling for models like the PC1010 1/2 HP electric compressor. It is specified for 120–230 VAC operation and targets a 95–125 PSI range, with a 125 PSI cut-out to stop tank pressure at set limits. The part number is 2E21025TB, and Senco lists it as an original replacement part designed to fit Senco air compressors, making it the proper choice for restoring accurate pressure control when the original switch leaks or fails.
