Page 62 | 1.1 Operating with Handles and Knobs Domed gear knobs GN 719.2 are very often used in place of ball knobs DIN 319 on switch levers, gear levers etc. Domed gear knobs satisfy by their form and ergonomical aspects. When using press-on type domed gear knobs (with bore B), a threaded shaft is not required. 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. see also... • Domed Gear Knobs GN 719 (Duroplast, with Thread) → Page 60 • Domed Gear Knobs GN 719.1 (Duroplast, Press-On Type) → Page 61 Information GN 719.2 Domed Gear Knobs 1 d 1 2 d 2 3 Color How to order (With thread) 1 2 3 GN719.2-20-M8-SW 1 d 1 2 d 3 3 Color How to order (Press-on type) 1 2 3 GN719.2-34-B10-RT • Plastic Technopolymer (Polyamide PA) - - Specification with thread Temperature resistant up to 80 °C - - Specification press-on type Temperature resistant up to 50 °C • Colors (shiny finish): Black, RAL 9005 SW Orange, RAL 2004 OR Gray, RAL 7035 GR Yellow, RAL 1021 GB Blue, RAL 5024 BL Red, RAL 3000 RT White, RAL 9002 WS • ISO Fundamental Tolerances → Page 2151 • Plastic Characteristics → Page 2158 • RoHS Specification 3 1 2 2 d 1 d 2 With thread d 3 Press on type d 4 h t 1 t 2 ±0,5 t 3 All colors, not in WS only SW, RT, WS only SW, RT 16 M  6 - B  6 - - 12 25 16 3,5 17      20 M  8 - B  8 - - 14 32 20 3,5 21      26 - - - - B 8 17 42 30 5   25 26 M  8 M 10 B 10 - - 17 42 30 5   30 34 M 10 M 12 B 10 B 12 -  21 54,5 35 8   40      Original design I.622 / I.622 N
