Application of yijia waterproof metal push button switch GQ19A with lock in CNC machine tools

  1. Application on main control panel
    On the main control panel of CNC machine tools, yijia GQ19A push button switch is often used for key operations such as start, stop and emergency stop. Its lock function can ensure that these important operations are not triggered by mistake, preventing production accidents.
  2. Application in complex environmental areas
    The processing area of ​​CNC machine tools is usually full of coolant, oil and metal chips, which puts strict requirements on the protection performance of the switch. The IP67 protection level of GQ19A push button switch enables it to work normally in this environment, ensuring the continuous operation of the machine tool.
  3. Application in safety protection system
    In order to protect the safety of operators and equipment, CNC machine tools are usually equipped with a variety of safety protection systems. GQ19A push button switches can be used to control these systems, such as the opening and closing of protective doors, the activation and release of safety interlocks, etc.

Differences between waterproof metal push button switches with locks and metal push button switches without locks

Waterproof metal push button switches with locks and metal push button switches without locks have significant differences in structural design, functional characteristics and application scenarios. Understanding these differences will help you make more informed decisions during selection and use. Here are their main differences:

Locking function

Metal push button switch with lock:

  • Locking function: The lock switch has a locking function, which can prevent the button from being misoperated by a physical lock (such as a key) or other locking mechanism.
  • Application scenario: Commonly used in important control links that need to prevent unauthorized or misoperation, such as emergency stop buttons, start buttons for key operations, etc.

Metal push button switch without lock:

  • No locking function: The lock switch does not have any physical locking mechanism, and the button can be directly pressed to operate.
  • Application scenario: Suitable for routine operations and occasions where misoperation does not need to be prevented, such as general start, stop, mode switching, etc.


Metal push button switch with lock:

  • High security: Due to the locking function, unauthorized personnel can be prevented from operating, ensuring the safety of equipment and personnel.
  • Misoperation protection: effectively prevent misoperation, especially in critical operations, to prevent accidental triggering or shutdown.

Unlocked metal button switch:

  • Lower security: no locking function, easy to be misoperated, especially in emergency situations may lead to accidents.
  • Limited scope of application: suitable for operations that do not involve safety risks, not suitable for occasions that require high security protection.

Protection performance

Locked metal button switch:

  • High protection level: usually with a high waterproof and dustproof level (such as IP67), suitable for harsh environments.
  • Strong durability: the design pays more attention to durability and is suitable for long-term use.

Unlocked metal button switch:

  • General protection performance: although it also has certain waterproof and dustproof performance, it is usually not as good as the locked switch.
  • Service life: relatively speaking, due to the lack of additional protection design, the service life may be slightly shorter.

Structural design

Locked metal button switch:

  • Complex design: the internal structure is complex, including locking mechanism, and the manufacturing cost is high.
  • Many operation steps: it needs to be unlocked with a key or other means before operation.

Unlocked metal button switch:

  • Simple design: the structure is relatively simple and the manufacturing cost is low.
  • Easy to operate: no additional steps are required, just press to operate, easy to use.


  • Metal button switch with lock: higher cost: due to complex structure and high protection performance, the manufacturing and maintenance costs are relatively high.
  • Metal button switch without lock: lower cost: simple structure, lower manufacturing and maintenance costs, more economical and practical.

There are significant differences between the waterproof metal push button switch with lock and the metal push button switch without lock in terms of function, safety, protection performance, structural design and cost. The lock switch is suitable for critical control occasions that require high safety and protection performance, while the non-lock switch is suitable for general operation, easy to use and economical. Choosing the right push button switch according to specific application requirements can effectively improve the safety and reliability of the equipment.
