How do Reed Switches Uniquely Perform?

Simple magnet interaction is the driving force behind the reed switch. Reed switches improve operations in a wide variety of low power devices. Moreover, increased demands for lower power devices have driven further growth for reed switch technology, since its introduction in the 1930’s. Today, switches can be customized for a high level of performance in an ultra-miniature design.

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 performance capabilities. First, the unique glass-to-metal hermetic seal allows these switches to exist and operate in almost any environment. Second, reed switches can survive extreme temperatures, moisture and workloads to deliver billions of reliable switching operations. This is a serious selling point in comparison to the environmentally limited mechanical and semiconductor switches.

Reed Switches Serve an Ever-Expanding Array of Applications

Because Standex reed switches feature unique durability and longevity, reed relays and sensors both utilize these components at the heart of their switching mechanism. An ever-expanding array of applications, and new reed relay, reed sensor and fluid level designs, are driving a greater need for reed switches across several industries. Here is a sampling of applications served by Standex reed switches:


Alternative Energy

From high voltage relays in solar panels to speed sensors on wind turbines, Standex reed switches are integral to alternative energy arrays.


Manufacturers of refrigerators, ranges, microwaves and washers and dryers rely on the power transfer, fluid level monitoring and other smart sensing capabilities offered by reed switch-dependent technologies.


Reed switches sensors effectively monitor fluids in passenger vehicles, as well as cargo position in freight vehicles.


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.
