Genuine DeWalt / Black & Decker Micro‑Switch N402543 – Replacement for DPC10QTC / Bostitch RC‑10SQ Compresso

This is the Genuine Micro‑Switch N402543, a high‑quality replacement component for certain DeWalt / Black & Decker compressors.

The micro‑switch is a small but essential electrical switch used inside the compressor’s control circuitry. It helps detect or respond to user input or internal safety thresholds (for example, pressure switch activation, on/off control, etc.), allowing the compressor to start, stop or switch modes safely. If this switch fails, the compressor may not start, may run continuously, or may not respond correctly to pressure settings or controls.

Because this is an OEM (Original Equipment Manufacturer) part, it is built to original specifications, ensuring correct mounting, electrical connection, and reliable operation.
