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.
