TL8503-02GA4

The TL SERIES is our large tactile series of knobs. The knobs design is based on the MS91528 tactile series of knobs, which not only gave the user a unique tactile feel but also were color coded. For avionic equipment color coding was not practical. This exact same series of knobs has been duplicated in a smaller size (See our TS series). With avionics equipment constantly shrinking in order to fit more in the cockpit, a small size knob was desirable. These units belong to the MS 21385 series of knobs. EHC meets the requirements of the MS specification and the Government drawing requirements. All of our backlighted knobs can be manufactured for night vision use. Our knobs meet NVIS Green A requirements.
