Universal On/Off Switch Knob
This switch knob fits most main power switches and is the same part listed elsewhere under BF_57, F_910, MAZ_54, P_234 and W_573 — different catalog numbers for the same physical part. It includes a mounting screw, but will also fit switch pins that don't have a threaded receptacle for one.
SPECIFICATIONS
- 5 x 5 mm square hole, 34 mm diameter (Bremas version)
COMPATIBILITY
- Fits: Most main power switches with a 5x5mm square pin (Bremas-style, 34mm diameter)
- Works with: W80099, the same knob without the included screw, for switches that don't need one
INSTALLATION
Simple push-on or screw-secured knob replacement — no tools beyond a small screwdriver if using the included screw.
PRO TIPS
- Confirm your switch pin measures 5x5mm before ordering — a slightly undersized square hole (common on some off-brand switches) means the knob will spin freely instead of gripping.
