Key features of NABCO HDS-A5 Push Button Switch
Intuitive and user-friendly operation
The HDS-A5 is designed to optimize usability for all users, including first-time users.
Large 70 mm push button for easy visibility and operation
Light operating force of approximately 6.5N for effortless use
Slightly raised button surface for easier tactile recognition
Stable push-button mechanism with fast and accurate response
During operation, users only need simple actions to operate the door easily without complicated instructions.
Clear status indication with LED display
The LED indicator system allows users to easily recognize restroom occupancy status from a distance:
Vacant: LED off – room available
Occupied: LED on – “Occupied” status displayed
When the restroom is occupied or locked, the outside display shows “Occupied” while the inside display shows “Locked,” allowing users to confirm that the door is securely locked throughout usage. From outside, users can easily identify the room status, helping reduce confusion and ensure privacy for the person inside.
In addition, the system provides step-by-step operation guidance, helping users follow the correct process more easily, especially in crowded public environments. The combination of LED indicators and audio guidance makes operation clear and minimizes confusion, even for first-time users.

The combination of audio guidance and LED indicators helps users operate the system correctly even in crowded spaces or on first use.

The device includes an overtime usage warning function (15–30 minutes) using flashing lights, allowing facility managers and people outside to easily recognize prolonged occupancy and help ensure user safety.
In emergency situations, the system can connect to an emergency call switch while also allowing the door to be opened from outside using a mechanical key or manual operation during power outages or system failures, ensuring that emergency access is always available when needed.
During use, the person inside only needs to press the button to lock the door, and the system automatically displays occupancy status through LED indicators for outside users to recognize. Clear status indications include: vacant – occupied – locked, helping avoid confusion even for first-time users.
Thanks to the combination of LED indication, audio guidance, and simple push-button operation, the HDS-A5 helps users operate the system easily while ensuring safety and privacy throughout usage.
