  • Single-point level switch operating on Archimedes' principle — a non-floating polypropylene displacer suspended from a billet-aluminium head changes weight as it submerges, actuating a 20 A S.P.D.T. micro-switch (rated to 500 VAC) through a magnetic isolator. No metal parts in contact with liquid, full IP67 housing.

  • A paddle flow switch with built-in digital timers that override the normally-off state of the switch and let a pump start in spite of an initial lack of flow. Includes an adjustable run-on timer that lets the pump ignore minor flow interruptions while still being fully protected against running dry.
