Reed Switches & Magnetic Switches

IMPORTANT NOTICE:

We are currently experiencing higher than normal order volumes at our Singapore warehouse. While all orders are being processed, some shipments may be delayed by 1–2 business days. Thank you for your patience and continued support.

Element14’s reed switches are electromagnetic devices that operate when exposed to a magnetic field. These switches are typically used for non-contact detection and are available in both normally open and normally closed versions.

Reed switches are highly reliable and compact, making them ideal for use in security systems, automotive applications, and proximity sensors. They offer a simple and effective way to detect the presence or absence of a magnetic field.

Applications:

Security Systems: Detecting the opening of doors and windows.
Automotive: Position sensors for automotive doors and windows.
Industrial Automation: Detecting the presence of objects on conveyor belts.
