Six product series built on one modular platform — flow, liquid level, temperature, pump control, relays and the components they are assembled from. Nothing is custom-fabricated; every configuration comes from stock parts.
Every series shares the same modular platform, so floats, stems, adapters and enclosures interchange across the range.
Compact piston-type magnetic reed flow switches. Angle body, straight body, low-flow, and visual indicator configurations. Five factory set points.
View Series 5 →Vertical and side-mounted liquid level switches. Single-point through four-level detection. Extended-stem, bulkhead, and flanged mounting options.
View Series 10 →Thermally-actuated switches using bimetallic disc technology. Creep-action sensing with 16 factory-set temperature thresholds.
View Series 11 →Liquid level switches that install through tank walls — no extended stem required. Popular with OEMs for low-level and differential sensing, from stock parts.
View Series 15 →Heavy-duty liquid level switches and control heads for pump-up and pump-down applications. Switches contactors, solenoids and motors directly.
View Series 20 →Solid-state AC relays, latchers and accessories. Amplify reed switch capacity for pumps, solenoids and valves, or protect contacts on reactive loads.
View Series 50 →Every Series 10 mounting and level configuration, each with its own page.
Flow, temperature and pump-control ranges broken out by product type.
Individual parts for field service, custom configurations and OEM fabrication. Every ERECTA SWITCH assembly comes apart.
If you know the tank, the medium and the load, the selection guide narrows the catalogue to a part number in four steps — including which switches need a relay or arc suppression.
