Reed Switches - Reed Switch Components

Standex Electronics produces a broad range of magnetic reed switches which are RoHS compliant - and many are UL recognized. From dry circuit switching to 70VA, from switching microvolt levels to switching 1,000 VDC, these switches are capable of tens of millions of trouble-free switching cycles. Our unique, patented, and highly automated production process allows us to produce very cost-effective switches with outstanding physical and electrical characteristics. In fact, our GR150 is the world's smallest magnetic reed switch.

Traditional, surface mount and overmolded versions are ideal for use within:

  • Proximity sensors
  • Fluid level sensors
  • Reed relays
  • Medical devices such as hearing aids and pill-shaped cameras
  • Consumer appliance
  • Commercial and industrial equipment
