The MS series of cable end float switches by Cynergy3 utilises a microswitch element activated by a moving stainless steel ball with lifetime of 200,000 operations. The switch is hermetically sealed within a HDPE casing filled with non-hygroscopic closed-cell polyurethane, enabling it to work as much as 100m deep in water. The MS series features a selection of contact forms (n/o, n/c and c/o), direct switching power and protective earth conductor included as standard (except for c/o versions). The switching element is UL, VDE and CENELEC approved. The switches are supplied with 5m length of WRAS approved cable with and can be operated in temperatures between 0°C and +45°C (WRAS approved to +23°C).

  • WRAS Approved Cable end float switch
