MS Series
The MS series of cable end float switches are designed for controlling levels in large tanks,
cisterns or reservoirs and can be directly installed on submersible pumps. The casing is
manufactured in blow moulded Polyethylene (HDPE), with 5m PVC cable with protective
earth conductor as standard*. The switching element is a microswitch, with UL, VDE and
CENELEC approvals, activated by a moving stainless steel ball and having an electrical life
of 200,000 operations. Non-hygroscopic closed-cell expanded polyurethane is injected
around the switch housing within the outer casing, hermetically sealing the unit. It is
capable of working down to 100 metres depth in water.
The “U” version with polyurethane cable is for use in fuel oils.
* = protective earth wire not included on “C” (C/O) versions.
