Standex Detect - Changeover Reed Switches
Reliable Break-Before-Make Switching with Form C Reed Technology
Changeover reed switches, also known as Form C or SPDT (Single Pole Double Throw) switches, feature three contact leads and operate with a break-before-make switching sequence. This means one contact disconnects before the other connects, ensuring clean signal transitions and reducing the risk of short circuits.
Changeover reed switches are ideal for applications requiring reliable switching between two circuits, such as signal routing, sensor feedback, and control logic.
These switches can be integrated into standard sensors and reed relay assemblies, and custom configurations are available to meet specific design requirements.

Hall effect proximity sensors detect magnetic fields and convert them into electrical signals. They offer high accuracy, durability, and are suitable for linear or angular position sensing in dynamic environments.
Single point liquid level sensors are designed to detect fluid at a specific level, typically a critical high or low point. These sensors use a single magnetic float and reed switch to provide a simple, reliable signal when the fluid reaches the designated level.
Available in vertical or horizontal mounting styles, these sensors are ideal for compact installations and are commonly used in tanks, reservoirs, and molded containers. They operate with minimal power consumption and offer high durability, with options for high-temperature resistance, IP-rated sealing, and high-power switching.
Their customizable design, cost-effectiveness, and ease of integration make them a dependable solution for fluid level monitoring across a wide range of industries.
High Power Magnetic Switching for Demanding Applications
The high-power reed switch series offers robust magnetic switching solutions capable of handling up to 120 W and voltages as high as 1,000 VDC. Designed for demanding applications, these reed switches are available in various sizes starting from 14 mm, including surface mount and through-hole options for flexible integration.
These switches are ideal for proximity, position, motion, and end-limit sensing, and can also be packaged into high power reed relays for enhanced durability and simplified PCB mounting. Relay packaging supports both pick-and-place automation and high insulation resistance, with some models exceeding 10¹³ Ohms.
Popular series such as KT, SHV, LI, and BE offer a range of contact configurations, including SPST, SPDT, and multi-switch designs. Whether used in automotive systems or test and measurement equipment, these high-power reed switches deliver reliable performance where high voltage and current demands are critical.
Custom solutions are also available to meet specific design requirements.
Dual In-line Package (DIP) Photo-MOSFET relays offering easy through-hole mounting and robust performance. Commonly used in industrial control, security systems, and test equipment.
Cylindrical proximity sensors are housed in round enclosures for easy mounting in tight or standardized spaces. Available with Reed or Hall effect technology, they provide reliable detection of magnetic or metallic targets.
Reed Relay Modules integrate multiple high-performance reed relays into compact, ready-to-use packages for efficient signal switching in space-constrained designs. Available in 8-channel configurations, these modules simplify circuit design by combining switching functionality with integrated driver electronics and advanced packaging.
The RM05-8A-SP Series features an 8-pole relay configuration housed in a dual-in-line through-hole package, equipped with MAX4823 integrated drivers and kickback protection—eliminating the need for external activation circuitry and reducing PCB footprint.
