Tapered knobs EN 518 do not require a thread at the shaft. During mounting, easy blows with a soft hammer are sufficient to drive the knob into place, the shaft end should be slightly rounded or chamfered (30°). The knobs sit absolute vibration-tight.
The transparent sight glass allows symbols to be placed underneath.
Once the knob is mounted on the shaft, the symbol is placed into the recess of the separately supplied sight glass and driven home with a soft hammer.
The symbol is fully protected from dirt and liquid by the tight connection between the sight glass and the knob.
Positioning and control symbols are to be ordered separately.
