The company’s optical liquid-level switches are made with flat glass, which eliminates contamination problems associated with the 90-degree cone normally used in these types of switches and provides a more reliable product, claims the company. These switches have full-line voltage capabilities and can operate at a 0.25- or 0.5-A load. The switch is available with an optional clip-style junction box attached. They have pipe threads or SAE O-ring seal configurations.
