Liquid Flow Switches What they do Detect liquid flow and provide a switch output to control or interlock equipment. Enable automatic responses in control systems when flow is present or absent. Key benefits Protect pumps and equipment from damage due to loss of flow. Improve process safety and reliability by signaling flow status to controllers or alarms. Support energy efficiency by preventing unnecessary operation when flow is not required. Simple integration with standard control circuits and equipment. Compatibility and applications Designed to work with common PLCs, relays, and control panels. Suitable for HVAC, water treatment, industrial processing, cooling loops, and other liquid systems. Available in configurations that support typical piping connections and installation environments. Size, material, and performance Compact form factor suitable for tight installation spaces. Built for robust operation in industrial environments. Delivers dependable switching performance across a range of flow conditions. Use scenarios Pump protection: detect loss of flow and trigger a shutdown or alarm to prevent damage. Process interlock: ensure a process cannot start unless verified flow is present. Monitoring and signaling: feed flow status to a control system or historian for tracking and alerts. Keyswitches What they do Provide authorized control of equipment or enclosures by requiring a key to operate. Key benefits Restricts access to critical controls, reducing the risk of unintended or unauthorized operation. Simple and reliable on/off control for powered equipment. Durable design suitable for industrial environments and routine use. Compatibility and applications Fits standard control panels, enclosures, and equipment that require a keyed start or stop. Works with common electrical circuits and safety interlocks as part of a secure control system. Suitable for manufacturing floors, data centers, utility rooms, and other facilities with restricted access needs. Size, material, and performance Compact, rugged housing designed for industrial use. Reliable electrical contacts and solid mechanical life for repeated operation. Multiple keying options to match existing security and control schemes. Use scenarios Enclosure security: restrict access to electrical panels to authorized personnel only. Startup control: require a key to start hazardous or risk equipment. Safety lockout: use as part of a controlled shutdown process to ensure deliberate reenergization.
