Panel indicators are a simple, practical solution for mounting an LED, neon or incandescent light source directly onto a user-interface panel for indication purposes. Panel indicators represent an easy and cost-effective way to provide a wide variety of indication messages on user-interface panels. Commonly used indicators show power “on” or “off” status whereas other indicators can communicate which cycle or function mode a piece of equipment is active in conveying a warning like “hot” or “safe to touch”.
