Fits most of the main power switches. This is the same part listed elsewhere as BF_57, F_910, MAZ_54, P_234 and W_573. Some switch pins have a female threaded receptacle for the screw that this knob comes with, but this knob will also fit the switches that do not have the threaded receptacle. 5 x 5 mm square hole, larger 34 mm diameter Bremas version. You may also use the W80099, it just doesn't have a screw.
