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.
