Schmersal joystick selector switches, available from AutomationDirect (Cumming, GA), have design features that make them suitable for food processing, pharmaceutical and medical applications. The joysticks comply with the special cleaning requirements of the food industry to prevent cross-contamination, particularly when used in machines that process raw goods.
The IP69K rating also makes the joysticks suitable for marine applications, traffic systems, commercial vehicles, and any dusty, dirty environments. Blue bellows versions are used in the food processing industry to assist in the detection of foreign materials, and gray bellows versions are used for other industrial and outdoor applications.
