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 (PEHD), 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.
Version with polyurethane cable is for use in fuel oils.
