Industrial 2-LH-110-120-360 Liquid Level Control Switch

BW Controls' 2-LH Liquid Level Control Switch is an industrial-grade switch designed to automate liquid-level control in tanks and process lines. The model specifies a 110–120 V line voltage with a 360 V secondary circuit, enabling it to drive downstream control devices in BW’s level-control systems. It is part of BW Controls’ liquid-level control family, which typically comprises a control relay, a level sensor (electrode or float), and an electrode holder to form a complete level-control loop. As a distributor-listed item, the 2-LH is documented as discontinued, reflecting its status in catalog and surplus markets. In practice, this switch provides reliable, electrically isolated level signaling for pump-down or valve-actuation applications in industrial liquid systems, where accurate level monitoring and straightforward integration with BW’s controllers and sensors are desired. BW Controls is an AMETEK brand, and the company emphasizes modular, sensor-driven liquid level control solutions that can be tailored to a variety of industrial processes.
