Kantech PB-EXIT Push Button with SPDT Switch
The Kantech PB-EXIT is a non-illuminated request-to-exit push button designed for seamless integration into access control systems. Built with a single pole double throw (SPDT) switch configuration, this device delivers reliable manual door release triggering for commercial and institutional security installations. The PB-EXIT eliminates powered illumination requirements, making it an ideal solution for retrofit applications and systems where simplified wiring and reduced power consumption are priorities.
Key Features
- SPDT Switch Configuration: Enables flexible switching logic supporting normally-open or normally-closed door control scenarios
- Non-Illuminated Design: Reduces power draw and eliminates illumination complexity in access control circuits
- Standard Push Button Form Factor: Compatible with existing rough-in openings and conventional access control mounting brackets
- Mechanical Switch Reliability: Proven contact design ensures consistent performance across high-cycle applications
- Straightforward Integration: Works directly with access control panels and relay logic controllers without additional interface requirements
Technical Specifications
The SPDT switch mechanism provides two separate circuit paths, allowing installers to configure the button for either momentary or maintained switching scenarios. The mechanical contact design is engineered for durability in high-traffic environments where frequent activation is expected. Standard electrical ratings support integration with typical 12V or 24V access control power supplies and relay circuits.
Applications
The PB-EXIT is deployed in secured doorways, controlled exits, and access-restricted areas requiring manual request-to-exit functionality. Common installations include office buildings, healthcare facilities, educational institutions, and data centers. The button serves as the interior-side trigger for electric strike plates, magnetic locks, and door release mechanisms controlled by access control panels.

I'll be direct: the PB-EXIT is about as straightforward as access control hardware gets, and that's exactly why it belongs in your installation toolkit. The SPDT switch gives you genuine flexibility—wire it normally-open or normally-closed depending on your panel's input requirements without hunting for a different part number. I've seen installers appreciate the non-illuminated design in retrofit scenarios where pulling additional power to the exit button location means opening walls you'd rather leave closed.
One practical consideration: verify your access panel's input voltage and switching logic before you order. Some panels expect a specific contact configuration for REX inputs, and while the SPDT gives you options, you need to know what your specific controller requires. Also consider user expectations—in very low-light environments, building occupants sometimes struggle to locate non-illuminated buttons. For most office and institutional applications with adequate ambient lighting, the PB-EXIT delivers reliable manual release triggering without the complexity of powered switches.
