Yijia YJ-GQ16 Metal Key-Lock Selector Switch is a high-quality product specially designed for industrial control. It combines the convenient operation of traditional push button switches with a key-lock function that significantly enhances device security and management efficiency.
Next, we will elaborate on the product’s application scenarios, functional features, and the advantages of Yijia’s industrial control products, giving you an in-depth understanding of why it is a reliable choice across various industries.
Product Application Scenarios
When you hear “YJ-GQ16 key-lock selector switch,” you might think it’s just an ordinary switch. Actually, its application range is very broad, and its functions are critical. Let’s take a look at its impressive performance in different environments:
1. Smart door locks and public facility security
Smart access control system
YJ-GQ16 key lock selection switch is widely used in smart door lock systems. It combines physical keys with switches to achieve dual security control. This function is very suitable for places with extremely high requirements for authority management, such as office buildings, data centers, and laboratories. It can only be operated by authorized personnel to prevent accidental touches and illegal intrusions, and effectively improve the overall security level.
Public transportation facilities
In public transportation hubs such as subway stations and airports, key operation panels (such as emergency power off, start-up, and maintenance modes) often use key lock selection switches to ensure that only authorized maintenance personnel can switch important working modes to prevent equipment failures and safety hazards caused by misoperation.
2. Industrial automation equipment
Industrial robots and automated production lines
In the operation of automated production equipment or industrial robots, YJ-GQ16 not only undertakes routine operations such as start/stop and mode switching, but also can realize the manual confirmation of important process steps through key locks. For example, during debugging or maintenance, it is necessary to switch to “manual mode” to reduce equipment misoperation and improve production safety and efficiency.
Machine tools and mechanical equipment
The operating tables of various CNC machine tools, elevators, cranes and other heavy mechanical equipment are usually equipped with key lock selection switches. Through key management, specific function operations (such as emergency stop, reset, key process start) can be restricted to ensure the safety of equipment operation and the implementation of management responsibilities.
3. New energy and energy storage system
Photovoltaic/energy storage system switching
YJ-GQ16 can be installed in new energy systems such as photovoltaic inverters and energy storage cabinets for scheme switching or emergency disconnection. The key lock design prevents unauthorized misoperation, facilitates maintenance and improves system operation and maintenance reliability.
4. Automotive electronics and special vehicles
Vehicle control and special function management
In the control panels of special vehicles such as police, sanitation, and engineering vehicles, key links such as emergency signal activation and power main switch are managed through key lock switches to achieve “human-machine separation” operation, improve electrical safety, and avoid accidental touches.
5. Fire emergency system
Fire alarm and emergency start
YJ-GQ16 is commonly used in fire alarm devices and emergency evacuation systems. Only personnel holding special keys can activate/reset the fire alarm system to prevent the equipment from being reset or misoperated at will.
| Application Field | Specific Scenario | Functional Value |
|---|---|---|
| Smart Access Control | Office buildings, data centers, laboratories | Key-based permission management prevents unauthorized operations and enhances security |
| Public Transportation | Subway stations, airports control & emergency equipment | Control of critical device modes minimizes misoperations and ensures reliable emergency response |
| Industrial Automation | Industrial robots, automated production lines, CNC machines | Mode switching and safety locking improve equipment security and operational efficiency |
| Mechanical Equipment | Machine tools, elevators, cranes | Limits critical function access ensuring safe operation and clear responsibilities |
| New Energy Sector | Photovoltaic inverters, energy storage cabinets | Prevents accidental operation, improves device stability and ease of maintenance |
| Special Vehicles | Police cars, sanitation trucks, engineering vehicles | Controls key functions to avoid accidental activation or unintended start-up |
| Fire Emergency | Fire alarm systems, emergency evacuation equipment | Dedicated key operation for arming and resetting ensures emergency devices aren’t misused |
These examples show that YJ-GQ16 is not just a “button” but a guardian in many industrial and public safety control systems. Its physical key-lock feature minimizes the risk of misoperation, protecting equipment and personnel safety.
