Mini Reed Switch N.C. (closed when magnet is near)


Part Number: VE-HAA28

Mini Reed Switch for alarm systems with leads.


  • Housing: gray ABS
  • Miniature magnetic switch NC
  • Screw mounting

Disclaimer about the 'normally closed' designation: This switch is classified by the manufacturer as being normally closed, but this terminology is ambiguous because there is no consensus on what the 'normal' state of a reed switch is. With this particular switch: when the magnet is nearby, the switch is closed; when the magnet is removed, the switch is open. The general opinion at Vetco is that this ought to be called 'normally open', despite the manufacturer's designation.
