How do Reed Switches Uniquely Perform?

Simple magnet interaction is the driving force behind the reed switch. Magnetic sensing doesn’t require external circuitry. Therefore, reed switches improve power efficiency. As a result, increased demands for lower power devices have driven further growth for reed switch technology, since the 1930’s. Today, switches are smaller than ever and feature the highest level of performance.

Multiple Reed Switch Actuation with rotating 2-pole magnet interaction

The Reed Switch and bar style permanent magnet are adjacent to each other. The magnets rotation and change in polarity actuate the Reed Switch multiple times.

Reed switches have unique switching capabilities. First, reed switches can exist and operate in almost any environment. This is because of their unique hermetic glass seal. Second, reed switches can survive extreme temperatures, moisture, and workloads to switch billions of reliable operations. On the other hand, mechanical and semiconductor switches are environmentally limited, making them prone to early failure.

Reed Switches Serve an Ever-Expanding Array of Applications

Because Standex reed switches feature unique durability and longevity, reed relays and sensors both contain the reed switch at the heart of their switching mechanism. New applications in reed relay, reed sensor, and fluid level designs are driving greater need for reed switches across several industries. Below is a sampling of applications served by Standex reed switches:

Alternative Energy

  • Standex reed switches are integral to alternative energy arrays. Uses include high voltage relays in solar panels to speed sensor on wind turbines, among others.


  • Manufacturers of refrigerators, ranges, microwaves and washers and dryers rely on reed switch technology. Reed switch-dependent technologies provide power transfer, monitor fluid levels and offer other smart sensing capabilities.


  • Reed switches sensors effectively monitor fluids in passenger vehicles, as well as cargo position in freight vehicles. Some example fluid level sensing applications include but are not limited to: brake fluid, coolant level, fuel level, and windshield washer fluid. Furthermore, reed sensors work in navigation and entertainment systems as well as automotive convenience applications.


  • An industrial facility requires electronic management of everything from its day-to-day operation and security to its HVAC and plumbing. Standex reed switches used in relays and sensors ensure daily operations perform smoothly.

Utility & Metering

  • Hermetically sealed reed switches precisely measure water flow, gas and electricity. A reed switch sensor is typically part of a feedback loop that sends a signal to the utility’s control center confirming that the meter has executed its commands correctly. Smart grid meters use reed switch-based sensors to detect whether the remote connect/disconnect system has functioned properly.


Firstly, Standex services each of these applications and more as the world’s largest manufacturer of reed switches. Furthermore, with greater than 50% market share, Standex offers the most comprehensive listing of reed switches available.

Secondly, Standex reed switches are impervious to almost all environments due to their hermetically sealed structure. Moreover, this opens up a vast number of unique applications that only reed switch technology can perform to, like mission critical operations.

Most importantly, new uses for reed switches continue to arise at a quickening pace as a result of their exemplary performance. Finally, solving complex problems through our Partner, Solve, Deliver® approach is why we exist!
