Direct Replacement Switch
The Superior Electric L39 push button switch replaces Makita part 651947-7 and Bosch 1607200146. It handles on/off and variable speed functions for compatible power tools. The four-terminal design manages electrical polarity for electric braking. This new aftermarket part is sold individually.
Upgrade Worn Components
Replace the original switch when mechanical internals degrade and cause intermittent operation or loss of variable speed control. The jump is worth it when the tool fails to start, runs at a single speed, or the braking function becomes unreliable. A fresh switch restores the full range of speed and safety features.
Simple Terminal Swap
The compact design fits the existing housing for straightforward installation. Transfer the four wire connections to the matching terminals on the new switch. The most common error is misplacing a lead, which reverses polarity and disables the braking function. Verify each connection against the tool's wiring diagram before reassembly.
