RUKO KES-FormC-75°-12.4mm SPDT Reed Switch

For engineers and technicians building position-sensing, proximity-detection, or low-power switching circuits, the RUKO KES-FormC-75°-12.4mm is a single-pole double-throw (SPDT) reed switch with pre-bent axial leads at a 75° angle. Its 12.4 mm glass body houses rhodium contacts, offering reliable switching in compact designs.

Why choose it

The 75° bent leads simplify PCB mounting in tight spaces, while rhodium contacts ensure long life and stable performance across a wide temperature range.

Ideal use cases

• Position and limit sensing in industrial equipment
• Proximity detection in security systems
• Low-power switching in battery-operated devices

Good to know

Reed switches are hermetically sealed, making them suitable for harsh environments. The SPDT configuration allows both normally open and normally closed circuits.
