  • Rugged yet simple design using proven materials
  • Hot and cold temperature operation
  • No temperature compensation or source regulation required
  • Highly reliable hermetic switches…over nine (9) billion operations
  • On-condition maintenance
  • AMETEK comprehensive customer service for spare parts and technical support


Float Level Switch
  • Wide Variety–available in over 200 service configurations
  • Flexible Design–can readily transform basic design components
  • Light Weight–typically weighs only 0.10 pounds without lead wires.
  • Small Size–some versions less than 0.75" diameter
  • No Mechanical Linkages–the unit contains only one moving part, the float assembly
  • Safety–switches are available with unique hermetically sealed inner housing for applications where current loads pose a safety concern in fuel tank applications
