Reed switches

Reed Switches are tiny magnetically operated switches used in many industries including Electronics and Communication (cell phones, PDA's, computers, copiers), Automotive, Appliances, Construction, Robotics and Toys.

Important parameters for reed switch performance:

  • Surface quality of the wire
  • Mechanical, magnetic and electrical properties
  • Fundamental properties for the switch to open close and conduct a current
  • The thermal expansion (CTE) of the wire within the hermetic glass seal
