Milwaukee Switch Lock Spring
Model Number: 40-50-0206
The Milwaukee 40-50-0206 is a genuine OEM Switch Lock Spring for the 0884-20 M18 Compact Blower. This small spring is the return spring for the blower's switch lock button: it provides the force that returns the lock button to its locked position and keeps the lock-out working so the blower is not activated accidentally. Because the spring cycles every time the lock button is used, it can weaken, fatigue, or break over time, at which point the lock button may not return or hold, and the switch lock-out stops working as intended. Replacing it with the genuine Milwaukee OEM spring restores the correct return force and lock-out action, where an off-spec spring may not fit the button cavity or provide the right tension.
This spring is identified as the Switch Lock Spring, Figure 7, on the Milwaukee service parts list for the 0884-20 M18 Compact Blower, serial F74A, F74B, and F74C, bulletin 55-05-0806, and it also serves the 0884-22 kit and 0884-059 service versions. It works directly with the switch lock button (42-42-0806, Figure 6), which it returns, and sits in the blower's switch area with the on-off switch; those related parts are separate items. If the lock button is not returning or holding, replace the spring and check the button at the same time. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
