DeWalt N190510 Spare Part - SELECTOR

Original DeWalt selector (part N190510) — a molded gear/selector that engages the gearbox to switch modes on compatible DeWalt rotary hammers; designed to replace a broken or worn selector and restore smooth gear changes and reliable operation.

Compact replacement dimensions are approximately 44 × 39 × 24 mm (approx.; listed as ~1.75 × 1.55 × 0.95 inches), making it a direct drop-in for the selector location on the listed models.
