Paxton Switch2 Door Access Control Unit - 405-321

The Paxton 405-321 Switch2 Access Control Unit is a compact and standalone door controller designed for managing access to a single entry point without the need for a network or PC. It’s a straightforward and secure solution for small-to-medium access control installations where simplicity, reliability, and scalability matter.

Switch2 works seamlessly with Paxton’s range of readers and keypads (such as the PROXIMITY and TOUCHLOCK series), allowing doors to be secured using cards, fobs, or PINs. The controller is mounted safely on the secure side of the door—typically indoors or in a protected cabinet—keeping sensitive electronics and memory inaccessible to tampering.

Programming is carried out using simple enrollment cards, eliminating the need for software or complex configuration. The system can store up to 10,000 users and supports time zones, anti-passback, and door open time adjustments when used with a compatible reader.

Built with robust circuitry and designed to withstand daily operation, this unit is ideal for controlling access to offices, stock rooms, schools, workshops, or utility spaces.
