Product Description
A Reed Switch is a small electromechanical device having two ferromagnetic reeds that are hermetically sealed in a glass envelope.  They range in length from 2.0 inches long to as small as  0.025 inches long.

We stock glass reed switch:-

1. 2 pin (SPST) Reedswitch
2. 3 pin (SPDT) Reedswitch

Available in Gold or silver pin.

Generally used glass sizes include:- 12mm-14mm, 18mm-22mm , 24mm-26mm, 52mm

Reed Contacts
  • The two reed leads are made up of Nickel/Iron (NiFe) alloy (52% nickel). 
  • To be affected by a magnetic field the reed leads must be ferromagnetic.
  • The three most popular materials in nature and easy to anneal are ferromagnetic: iron, cobalt, and nickel.
  • The tips of the two reed contacts are either plated or sputtered with rhodium, ruthenium or iridium, with an under layer of either gold, copper or Tungsten.
