The Senco 2E21013TBQJ Pressure Switch with Unloader is a genuine Senco replacement part designed for air compressors, specifically compatible with Senco PC0968 units. It provides a 95 psi cut‑in (on) and 125 psi cut‑out (off) sequence and includes a single‑port unloader valve that vents the pump head to speed restart when the compressor shuts down. This configuration enables reliable automatic operation on compatible Senco models that use the 2E21013TBQJ switch, delivering consistent pressure control for workshop pneumatic tools.
