Genuine 1 Switch Comp DTD154 Impact Driver

The Makita 143975-1 Switch Comp is a genuine Makita replacement part designed to restore reliable trigger control to a faulty DTD154 cordless impact driver. Manufactured to Makita's own standards, it provides a direct-fit solution for tradespeople looking to return a worn or non-responsive tool to full working order without modification. Featuring a robust polymer housing with quality metal contacts, this switch assembly handles the repeated starts and stops typical of demanding site work. It restores both on/off function and smooth variable trigger response, helping maintain consistent torque delivery under load — particularly important where controlled fastening is required. Compatible with the DTD154 and selected DTD153 variants, the switch is designed to install using existing connectors and mounting points. This makes it a practical choice for contractors and maintenance professionals looking to extend the service life of their impact driver and reduce costly downtime on site. Supplied as a single switch component for targeted repair.
