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.

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.

The high frequency reed switch series is engineered for precision switching in RF and high-speed digital applications. These switches are optimized to handle signals from DC up to 7 GHz, making them ideal for use in telecommunications, computing, and advanced test equipment.

With nickel/iron leads offering high magnetic permeability, these reed switches deliver exceptional linearity across a broad frequency spectrum. Their compact form factor allows for high-density PCB mounting, and internal shielding ensures minimal electromagnetic interference, even in tightly stacked configurations.

These switches are commonly integrated into high-frequency reed relays for enhanced durability and performance.
