Dewalt 90588959 Switch Trigger Spring

Product Description

The DEWALT 90588959 is a replacement switch trigger spring designed to restore proper trigger function in DEWALT power tools. This small but critical component maintains the return tension on the switch trigger assembly, ensuring the trigger resets correctly after each use. It is typically installed by power tool repair technicians or experienced trades professionals performing tool maintenance. When the original spring loses tension, breaks, or becomes deformed, tool trigger response becomes unreliable, making this OEM-style replacement part a straightforward fix to restore safe operation.

This switch trigger spring is a service part intended for DEWALT power tools requiring trigger mechanism repair. It is suited for shop-level repair work or field maintenance performed by trades professionals who service their own tools. Installation is most common when a trigger fails to return to the off position or exhibits sluggish response due to spring fatigue or damage.
