Features

  • Reed switch ensures high reliability and long life duration.
  • Materials such as stainless steel and corrosion-resistant resins (PVC, PP, PTFE) enable various purposes of use.

Operating Principles

Float contains magnet and the stem contains reed switch. UP/DOWN movement of the liquid surface makes the reed switch ON/OFF with the magnet inside the float. The stoppers at the top and the bottom of the float limit the movement range and keep the self holding of the contact operation.
