The Makita 650722-8 is a genuine replacement trigger switch designed to restore reliable power delivery and speed control in Makita cordless impact drivers, including the BTD134 and BTD146. When a trigger switch begins to fail, the symptoms are hard to ignore — intermittent starts, complete no-start faults, or inconsistent speed response under load. This genuine Makita part addresses those issues directly, replacing the original switch assembly like-for-like to bring the tool back to full working order. Constructed with a tough polymer body and metal contact elements, the switch is built to handle the demands of regular professional use on site and in the workshop. The compact assembly seats neatly within the original handle cavity, requiring no modification and following the standard wiring layout for a straightforward installation. This part is the correct choice for contractors and tradespeople who rely on their Makita impact driver daily and need a dependable, manufacturer-approved fix rather than an aftermarket alternative. It is also suitable for home workshop users carrying out their own tool maintenance.
