Industrial panel mount indicators (also known as switch indicators) are instruments used to show the status of a process or system. They are designed to be mounted on a control panel and installed in machine panels, in automation systems, or in industrial machinery. They typically use LEDs or LCDs to indicate operating status, passed/failed results, temperature readings, etc. Industrial panel mount indicators/switch indicators often come with an array of features, such as programmable logic controllers (PLCs) to do calculations in complex processes, and a touch screen interface to make it easier to input commands. Additionally, they may include additional indicators such as needle meters, digital displays, and alarm notifications.
