Locking Metal Push Button Switch MS19

19mm Locking Metal Push Button Switch is designed for equipment that requires a clear and maintained ON/OFF control position. 

It features a 19mm mounting size, a raised mushroom head, a self-locking function, and solder lug terminals. Compared with a standard flat-head push button, the mushroom head provides a larger and more prominent operating surface. This makes the switch easier to identify and press, especially when operators need to react quickly or are wearing gloves.

The self-locking mechanism is useful for equipment where a stop or lock signal needs to remain active after the button is pressed. Instead of returning immediately when the operator releases the button, the switch maintains its locked state until it is intentionally reset.

Key Features

1. 19mm panel mounting size for equipment control panels

   Mushroom head with a larger and more visible operating surface

2. Self-locking function for maintaining the selected switch state

3. Solder lug terminals for panel wiring and PCB/control circuit connection

4. IP67 protection for applications where dust and water resistance are required

5. Raised head design makes the switch easier to locate and operate with gloves

Basic Specifications

The core advantages of the 19 mm metal mushroom pushbutton switch include a metal housing, IP65/IP67 protection on the panel side, and a highly visible large actuator, making it particularly suitable for machinery control panels, automated production lines, safety control and power cut-off applications.

The self-locking structure is another important feature for laser, dispensing, and testing equipment.

A conventional momentary push button returns to its original position after the operator releases it. This may not be suitable when a stop or lock command needs to remain active until the equipment is intentionally reset.

With a self-locking switch, pressing the button can maintain the stop or lock state. During maintenance, troubleshooting, or abnormal equipment conditions, the locked position can help prevent the machine from immediately returning to operation when the operator releases the button.

The actual machine control logic should still be designed so that resetting the button does not automatically restart the equipment. A separate start command or other appropriate control condition should be required before normal operation resumes.

Applications

The Locking Metal Push Button Switch 19mm can be considered for:

• Laser processing equipment

• Laser marking machines

• Glue dispensing equipment

• Automatic dispensing machines

• Testing and inspection equipment

• Industrial automation equipment

• Equipment control panels

• Machine maintenance control systems

FAQ

Q1: What is the mounting size of this locking push button?

The switch uses a 19mm mounting size. The actual panel cut-out should be checked against the product drawing before machining the control panel.

Q2: Is the 19mm metal push button momentary or locking?

This model uses a self-locking function. Once pressed, the switch remains in its selected position until it is operated again to release the lock.

Q3: Why is a mushroom head used?

The mushroom head provides a larger and more prominent operating surface than a standard flat-head button. It can make the switch easier to locate, identify, and press, particularly when operators are wearing gloves.
