Provide a keyed control point for an automatic door operator at a narrow mounting location. Security Door Controls AUTO-KSN is a narrow automatic-operator key switch used where authorized personnel need a physical, key-operated command at an automatic entrance. Its narrow profile addresses openings where the available mounting area does not suit a wider control station. The switch fits automatic-door applications that require a controlled activation point separate from an ordinary push plate or other public activation device. Typical placements include a door-frame area adjacent to an automatic opening, a secured staff entrance, or another access-controlled location where operation should be limited to personnel with the appropriate key. The key-switch format provides a deliberate manual control action at the opening. AUTO-KSN is distinguished within automatic-operator control hardware by its narrow configuration. That format makes it relevant when frame width and control-station space drive component selection. Match the switch to the automatic door operator control interface and the mounting conditions at the specific opening. The component is intended for the automatic-operator control function rather than as a general-purpose door lock or public-access activation control.
