Milwaukee Terminal Block Spring
Model Number: 40-50-1090
The Milwaukee 40-50-1090 is a genuine OEM Terminal Block Spring for use in compatible Milwaukee tools. The terminal block spring is a small precision spring used within an electrical terminal block assembly — applying consistent contact pressure to maintain a secure, low-resistance electrical connection between conductors and the terminal block contacts. Terminal block springs are used in the wiring assemblies of corded and cordless tools where multiple conductors must be terminated and connected reliably. The spring must maintain its contact force throughout the thermal cycling and vibration of tool operation to prevent intermittent connections or increased contact resistance that could cause overheating or erratic tool behavior. A broken or fatigued terminal block spring that can no longer maintain proper contact pressure requires replacement to restore reliable electrical connections.
Using a genuine Milwaukee OEM terminal block spring ensures the correct wire diameter, spring rate, and geometry for the terminal block it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct terminal block spring for your specific unit.
