Coolant Level Switches

Passive level switches are devices that monitor a fluid level based on a non-contact magnetic float:

  • Protect systems from overfilling or damage
  • Control activation and deactivation of devices to avoid their damage due to high or low fluid level
  • Activate devices based on a fluid level (e.g., warning light)

Available in different contact arrangements and mounting variants

  • Horizontally mounted (side), SPST normally closed, normally open - finger switch
  • Vertically mounted (top, bottom), SPST normally closed, normally open, with drain plug (bottom mounted) - float switches
