Float Switches

The HFS Series Hyjet Float Switch, which utilises an innovative, yet simple, foolproof switching concept, has greatly enhanced Float Switch reliability. The positive micro-switching eliminates the possibility of more than one circuit operating simultaneously.

The design innovation of the switch is the ‘sliding detent’ action which obviates wave-induced oscillation (common in mercury-type switches) while maintaining consistency in switching level accuracy. The smooth, robust ABS switch housing on the HFS model prevents the adhesion of foreign materials.

• Secure cable at appropriate height to ensure desired switch levels are achieved.
• The differential between switching On / Off or Off / On can be adjusted by moving the cable weight relative to the Float Switch. The further the weight is situated from the Float Switch the greater the ‘switching differential’. Set up to suit the particular application.
