Momentary Metal Push Button Switch with LED MS19

19mm momentary metal push button switch LED is a panel-mounted control switch designed for PLC control cabinets and industrial automation equipment. It combines a compact flat head, red ring LED indicator, momentary reset function, metal housing, and IP67 protection in one control component.

Unlike a latching push button, this momentary switch returns to its original position when the operator releases it. This makes it suitable for control circuits that require a short pulse or temporary command, such as triggering a PLC input, relay, reset signal, or other programmed operation.

The red ring LED provides a clear visual indication on the control panel. It can help operators quickly locate the switch in low-light conditions or on panels containing multiple buttons, indicators, and control devices.

Product Features

1. Momentary Reset Function

The switch returns to its original position after the operator releases it. This makes the 19mm momentary metal push button switch led suitable for applications where the control system only needs a short input signal rather than a continuously maintained ON state.

For PLC applications, the switch can be used for functions such as trigger commands, reset inputs, manual operation commands, and other short-duration control signals.

2. Red Ring LED Indicator

The red ring LED provides a visible indication around the switch head. Compared with an unlit button, the illuminated ring can make an important control point easier to identify on a busy industrial control panel.

The LED can be configured according to the control circuit and selected product version. Its actual indication function can be defined by the equipment manufacturer, such as operation status, warning indication, or control-point identification.

3. Flat Metal Head

The flat-head design keeps the switch relatively compact on the panel surface. It is suitable for control cabinets where several switches and indicators need to be arranged within limited panel space.

The metal housing also provides a solid operating feel and is suitable for equipment that requires a more durable panel-mounted switch.

4. IP67 Protection

The IP67-rated construction provides protection against dust and temporary water immersion under specified test conditions. This makes the switch suitable for industrial control panels that may be exposed to dust, moisture, oil contamination, or frequent manual operation.

The actual protection performance also depends on correct panel installation, sealing, and the overall enclosure design.

5. Solder Lug Terminals

The solder lug terminal design provides a straightforward connection method for control-panel wiring. It can be integrated into PLC, relay, and other low-voltage control circuits according to the electrical configuration of the selected model.

Applications

The 19mm momentary metal push button switch led is mainly designed for industrial control and automation applications, including:

• PLC control cabinets

• Industrial automation equipment

• Machine control panels

• Production line equipment

• Electrical control cabinets

• Testing and inspection equipment

• Automated machinery

• Industrial control systems

• Equipment reset panels

• Manual trigger and command panels

What Problems Does It Solve for Equipment Manufacturers?

1. Avoids Unwanted Continuous Activation

Some control commands only need to be active for a short period. A latching switch can remain electrically or mechanically engaged after the operator releases it, which may not be suitable for these applications.

The momentary reset function allows the switch to return automatically after release, helping equipment designers implement short-pulse or temporary control logic.

2. Makes Important Controls Easier to Identify

Control cabinets often contain multiple switches, indicator lights, displays, and circuit components. A red LED ring provides an additional visual reference around the button.

This can help operators locate a specific control point more quickly, particularly when the panel is installed in a dimly lit or visually complex environment.

3. Fits Compact Control Panels

The flat-head design has a relatively compact profile compared with larger raised or mushroom-head buttons. This gives equipment manufacturers more flexibility when arranging multiple controls on a limited panel surface.

The 19mm mounting size is also suitable for many compact industrial control panel designs.

4. Provides Protection for Industrial Environments

Industrial equipment may encounter dust, moisture, oil, vibration, and repeated manual operation. The IP67-rated metal push button is designed for applications where panel-side protection is an important selection requirement.

Correct installation and panel sealing remain important to achieve the expected protection level.

5. Simplifies PLC and Relay Input Control

The momentary contact can be used to provide a short control signal to a PLC or relay circuit. This is useful for functions such as:

• Start or trigger commands

• Reset inputs

• Manual control

• Step operation

• Test commands

• Short-duration activation

FAQ

Q1: What is a 19mm momentary metal push button switch?

A 19mm momentary metal push button switch is a panel-mounted switch with a 19mm mounting size that returns to its original position after being released. It is commonly used when a control circuit requires a temporary signal rather than a maintained switch state.

Q2: Does this switch stay ON after pressing?

No. This model uses a momentary/self-reset function. The switch returns after the operator releases it.

Q3: What is the purpose of the red ring LED?

The red ring LED provides a visual indication around the switch. It can be used to identify an important control point or indicate a user-defined operating, warning, or control status.
