N485853 supersedes older part numbers: 326087-01

Original DeWalt N485853 — Replacement Power/Trigger Switch for demolition hammers

Short description

- This is the original DeWalt N485853 electrical switch used in DeWalt SDS‑max/demolition hammers. It is the factory switch that controls motor power (momentary on/off action) and is supplied to match the tool’s wiring and mounting points.

What it is (specifics)

- Type: Two‑pole switch assembly (DPST-style) with spring return / momentary on–off action — designed for hammer-drill duty. Rated for heavy tool use.

- Alternate / factory cross reference: 326087‑01 (commonly shown as the replacement/reference number for N485853).

Fits (example models)

- Common DeWalt models this switch is used in: D25899K, D25900K (and variants D25900KAR, D25900KB2), D25940K (and variants D25940KAR, D25940KB2) and D25941K. Use these model/type listings to confirm fit for your specific tool variant.

Why this part matters

- If your hammer won’t start, has intermittent power, or the original trigger feels loose/fails to spring back, replacing the N485853 returns the tool to factory control characteristics — same form, fit and electrical connections as the original switch used in those DeWalt demolition hammers.

Quick installation note

- The switch is a direct replacement designed to mount in the factory housing and connect to the original wiring harness; typical replacement requires disassembly of the tool’s main housing and basic hand tools. (If you’re not comfortable with internal wiring or safety procedures, have a qualified service technician install it.)
