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.

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.
High density matrix reed relays are designed for ultra-compact, high-channel-count applications where space efficiency and performance are critical. With footprints as small as 4.35 × 4.35 mm, these relays enable dense relay arrays, up to 1000 relays on a 12” board, ideal for IC wafer testing, functional PCB test systems, and data acquisition platforms. Featuring low power consumption, fast switching speeds, and optional shielding configurations, they offer reliable performance in demanding environments. Their modular design supports vertical and horizontal stacking, making them a versatile solution for high-density signal routing and matrix switching.
- The BX2 Series of edge-lit backlights provides a highly diffuse source of illumination, packed within a thin and thermally efficient housing.
- The BX2 allows for configuration with polarization or collimation. A backlight configured with collimation is best suited for applications requiring a higher degree of edge clarity when imaging object silhouettes.
- This second edition of our edge-lit backlight series is more than twice as bright as previous BX and CX models.
- As with most planar backlight designs, this product is useful for edge detection, part location & orientation identification, presence & absence, hole detection and object gauging.
Optimized for high-speed signal transmission and minimal signal distortion, these relays feature low off-state capacitance, making them ideal for RF, telecom, and precision measurement applications.
