ELMA 500 configurations of knobs in various styles are available as push-on, set-screw, collet, wing, bell-shaped, aluminum, locking, and specialty knobs. Product series serves the two-communications, medical, industrial, audio, military, and instrumentation markets. Product’s have specialty features such as unique shapes, a soft-touch feel, ergonomic design.
