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.
