Standex Detect - Bistable and Latching Reed Switches
The latching / bi-stable (1 Form E) reed switch is a magnetically operated switch designed for ultra-low power applications, particularly in battery-powered and energy-sensitive systems. Unlike traditional reed switches, this bistable variant maintains its contact state, either open or closed, without continuous power, thanks to its dual-magnet latching mechanism.
The switch operates by using two permanent magnets: one partially magnetized to bring the contacts near each other, and a second magnet that controls the contact state by reversing its magnetic field. This design allows the switch to remain in either the normally open (N.O.) or normally closed (N.C.) state until actively changed, making it ideal for applications requiring stable switching with minimal energy consumption.
More Product Information
Continuous level sensors provide real-time monitoring across the entire height of a fluid container. These sensors use magnetic reed switches mounted along a PCB, combined with resistors to generate discreet voltage outputs. As a magnetic float moves along the sensor stem, it activates multiple reed switches, enabling precise and uninterrupted tracking of fluid levels. Advanced models like the CLS and HLS series incorporate capacitive or Hall effect technologies for high-resolution, programmable outputs in harsh environments.
Ultra-Compact Reed Switches for Precision Electronics
The ultraminiature reed switch series offers some of the smallest magnetic switching solutions available, with glass body lengths starting at just 3.95 mm. These switches are engineered for precision and reliability in space-constrained environments, making them ideal for miniaturized electronics and high-density circuit designs.
Despite their compact size, these switches maintain strong electrical performance thanks to advanced contact materials and hermetically sealed construction. Their flat lead design supports automated assembly processes such as surface mounting and tape-and-reel packaging, enabling efficient integration into high-volume production lines.
Commonly used in semiconductor testing, medical devices, telecommunications, security systems, and automotive electronics, these switches provide dependable magnetic actuation in applications where size, sensitivity, and durability are critical.
