The QH-series of illuminated halo indicators are APEM's latest innovation in the expanding range of LED indicators. Designed to energize and impress users with a stylish visual affect, the QH halo uses optimal, high-quality, hyper-bright LEDs and are available in a number of different frames and color options. The QH-series halos are used as a status indicator with APEM's 16 mm, 19 mm, and 22 mm switches, from LED indicators to industrial emergency stops. Used in either interior or exterior applications, the QH halos are easy to mount with zero depth from behind the panel and are held to the panel by the nut of the switch and an adhesive gasket for an IP67 rating.
