Knurled rim enabling a secure grip for precise adjustment.

White position pointer


34mm Diameter 

10mm Push Fit 

To suit a 4mm Diameter D shaped shaft. (See photo’s)

The D socket column is 11mm in diameter

and is much deeper than the rim of the knob @ 19mm

Depth of socket for shaft approx 17mm

Made from a tough plastic the  ‘D’ socket on the knob is very sturdy being reinforced with a tensile steel clip ring

 The rotary switch we show in the photographs above has a solid multi switching action which the knob copes with easily.

 Please note:- When fitting the knob to the shaft these are so solidly put together that quite a lot of force is required.

If replacing a broken knob check that the D shaft is 4mm and most important check that the shaft hasn’t seized (quite often this is why the old knob breaks) if it moves freely then this replacement should be fine and as our minimum quantity is 2 – you get a spare!

These knobs are multi-purpose 

Suiting applications from the precise adjustment of potentiometers/tuning controls on radio’s etc. to domestic appliance switches cookers etc. 

Basically if the shaft you need a knob for looks like the one pictured above, then problem solved.
