LED Metal Push Button Switch MS40

LED Metal Push Button Switch 40MM is a large-size illuminated metal push button designed for equipment panels.

LED Metal Push Button Switch with a 40mm mounting size, flat head, circular LED ring, solder terminals, and IP67 protection, it is suitable for self-service terminals, parking payment machines, information kiosks, elevator control panels, and industrial equipment.

The large button surface is quick to locate and press, while the surrounding LED ring provides a clear visual indication of the button status. Different LED colors can be used to distinguish operating conditions such as available, occupied, active, or fault status. This makes the switch practical for equipment interfaces where users need to understand the control state at a glance.

Key Features

Large Button with Clear LED Ring Indication

The main advantage of a 40mm illuminated button is the combination of a large operating surface and visible status feedback. On a self-service machine or public-use control panel, users may not be familiar with the equipment interface. A large button with a bright LED ring can make the operating position easier to identify.

The LED ring can also be assigned different colors for different equipment states. For example, green can indicate that a function is available, while red may indicate a stop, occupied, or fault condition. The exact indication logic is determined by the equipment controller and application requirements.

This makes the switch useful when the button itself needs to provide both physical control and visual feedback.

IP67 Protection for Public and Industrial Equipment

The LED metal push button switch 40MM is designed for applications where the control panel may be exposed to dust, moisture, or regular cleaning.

With IP67 protection, the switch provides dust-tight protection and resistance to temporary water immersion under the conditions defined by the IP rating. Proper panel installation and wiring are still important because the protection of the complete equipment depends on the enclosure, mounting structure, and cable connection.

This feature is particularly useful for outdoor or semi-outdoor self-service equipment, public facilities, and industrial control panels where environmental exposure is a concern.

Momentary and Contact Options

The standard reset or momentary version returns to its original position after the button is released. This makes it suitable for control functions that only need a signal while the button is being pressed.

Depending on the circuit design, contact configurations such as 1NO+1NC and 2NO+2NC can be selected. Normally open and normally closed contacts can be used for different control and monitoring requirements.

For applications that require maintained ON/OFF operation, a latching version may also be considered. Buyers should confirm the required switching function before ordering, especially when the button is integrated into an automated control system.

LED Ring Voltage and Color Options

The circular LED is available in different voltage and color configurations. Common LED operating options include DC 3–48V and AC 110–120V, depending on the selected model.

Common colors include:Red, Green, Blue, Yellow, White

Custom LED voltage and color options may also be available for specific projects. For equipment manufacturers, it is important to specify the actual control voltage and LED wiring requirements when requesting samples or quotations.

Typical Applications

The 40mm illuminated metal button is suitable for equipment that requires a large, easy-to-recognize control interface.

Typical applications include:

• Self-service ticket machines

• Parking payment machines

• Information kiosks

• Elevator control panels

• Public-service terminals

• Industrial control panels

• Automation equipment

• Outdoor or semi-outdoor equipment

• Equipment status control panels

For self-service equipment, the LED ring can provide a simple visual guide for users without requiring additional indicator lights on the panel.

Why Use a 40mm LED Metal Push Button?

A 40mm button is generally selected when visibility and ease of operation are more important than saving panel space. The large button surface is easier to locate, while the LED ring provides a second visual layer for status indication.

For public equipment, this combination can reduce uncertainty during operation. Users can identify the button quickly and understand its current status through the illuminated ring.

For equipment manufacturers and project contractors, the switch also combines the button, metal panel interface, and LED indicator into one component, which can help simplify the control panel layout.

FAQ
