OEM SB1B Exit Button NO/NC/COM

OEM SB1B Release Button

The OEM SB1B Exit Button serves as a critical interface component for professional access control systems requiring reliable egress signaling. This momentary contact switch utilizes a Form C relay configuration to provide versatile integration options. It supports both Normally Open (NO) and Normally Closed (NC) circuits through a shared Common (COM) terminal. This electrical design ensures compatibility with fail-safe and fail-secure locking hardware. The internal mechanism facilitates rapid signal transmission to door controllers or power supply units. Engineers can deploy this unit to trigger electromagnetic locks or electric strikes across diverse commercial environments.

The device housing consists of high-impact, fire-retardant ABS plastic for structural integrity. It adheres to the standard 86mm square footprint common in European and African electrical installations. This standardized dimension allows for flush mounting using standard backboxes or surface mounting where wall depth is limited. The tactile response of the push plate provides immediate physical feedback to the user. Its internal spring system is rated for high-frequency operation in high-traffic zones. The white finish maintains a neutral aesthetic for professional office corridors and server room entry points. Terminal connections use secure screw-down blocks to prevent wire slippage during vibration or maintenance.

Electrical performance remains stable under varied environmental conditions. The switch handles a maximum current of 3 Amperes at 36 Volts DC. This rating accommodates the inductive loads typically associated with security solenoids and relay coils. Low contact resistance ensures minimal voltage drop across the signal path. The unit operates effectively in temperatures ranging from -10 to +55 degrees Celsius. Humidity resistance up to 95 percent non-condensing allows for installation in non-conditioned industrial spaces. The mechanical life expectancy exceeds 500,000 cycles under normal operating parameters. This durability reduces the total cost of ownership by extending replacement intervals in active facilities.
