INTRODUCTION
Elma classic collet knobs are available in 7 different
diameters. Knobs with diameters of 10 to 28 mm are
stocked in two versions; with and without wings. Both
versions are available with a line as an option.
The knobs are fi xed onto the shafts by means of the
proven collet tightening method.
The tightening elements for knobs with diameters of
10 mm and 14.5 mm are hidden from view by nut cov-
ers. For the larger knob types, concealment of
these elements is ensured by the special Elma design.
Furthermore, two different switches can be operated by
inserting one knob on top of the other (concentric style).
Knobs with diameters of 14.5 to 36 mm are designed
to enable the next smallest knob to fi t onto it. When
dual knobs are used, the larger of the two must be
equipped with a collet with through-hole.
