When you choose a 22mm metal push button switch with a 12V LED, you are deciding how your whole control panel will feel, look, and perform in the field. This guide walks through selection, wiring, and recommended models in a friendly, engineering-focused way, so you can send a confident RFQ or finalize your BOM without guesswork.
What Is a 22mm Metal Push Button Switch?
A 22mm metal push button switch is a panel‑mount control device designed for a 22 mm mounting hole, typically used in industrial control panels, machinery dashboards, vehicles, and power distribution boxes. The 12V LED version integrates an indicator light (ring, dot, or symbol) that runs from a 12V supply, making status indication simple and compact.
Compared with plastic push buttons, a YJ-GQ22B metal 22mm switch provides higher mechanical strength, better scratch resistance, and a more premium look, which is why it is popular in harsh environments and high‑end equipment front panels. Many suppliers market these as “anti‑vandal” switches, aimed at public terminals, kiosks, EV chargers, and access control equipment.

How to Select the Right 22mm Metal Push Button Switch (12V LED)
Before requesting prices or samples, it helps to define your application clearly. That is how you avoid back‑and‑forth emails and mis‑matched samples.
Key Selection Factors
From an engineer or procurement perspective, a 22mm metal push button switch should be specified along at least these axes: Download YJ-GQ22B specification sheet
- Panel and mechanical constraints
- Electrical ratings and contact form
- LED requirements (12V LED indicator)
- Switch action: momentary vs latching
- Environmental and protection ratings
- Standards and approvals
If you already know your panel voltage, contact logic, and operating environment, feel free to send a quick inquiry with those points; manufacturers usually respond faster when your spec is clear.
Selection Checklist Table
| Requirement | Typical Choice for 22mm Metal Push Button (12V LED) |
| Panel cut‑out | 22 mm round hole |
| Operation | Momentary (spring return) or latching push‑on/push‑off |
| LED voltage | 12V DC LED ring or dot |
| Contact configuration | 1NO + 1NC for industrial control signals |
| Rated load | Up to 5–10A at 250VAC or 24VDC, depending on model |
| Protection | IP65–IP67, metal bezel for anti‑vandal use |
| Certification | UL / CE / CSA / TUV for global projects |
Wiring a 22mm Metal Push Button Switch with 12V LED
This is where most engineers or hobbyists get nervous: “Which pin is the LED? Which is NO?” Good news: the logic is simpler than it looks once you understand the terminal layout.
Typical Terminal Layout
Many 22mm 12V LED metal push button switches use separate pins for LED and switch contacts.
- Switch pins:
- COM (common)
- NO (normally open)
- NC (normally closed), if available
- LED pins:
- LED+ (anode, often marked with “+” or symbol)
- LED− (cathode, often marked “–”)
Some high‑current models have YJ-GQ16 Illuminated knob screw terminals; others have solder lugs or PCB pins, but the electrical concept is the same.
Basic 12V LED Push Button Wiring (Momentary, 1NO1NC)
Below is a generic logic description of wiring a 22mm metal push button to control a 12V load (for example, a relay coil, light bar, or controller input) while powering the LED.
- Connect the 12V supply positive to:
- Connect the load:
- Connect LED− terminal:
In many ready‑made 12V LED switches, the resistor is already integrated for 12V operation, so you can connect LED+ directly to 12V. Always check the datasheet to avoid burning the LED.

Common Wiring Modes Table
| Wiring Mode | LED Behavior | Switch Function (NO) |
| LED always on | LED wired to 12V and GND directly | NO connects 12V to load when pressed |
| LED on only when pressed | LED− tied to NO, LED+ to 12V | Pressing sends 12V to both LED and load |
| LED inverse (on when OFF) | LED across NC and 12V | LED turns off when circuit energizes |
| LED powered from separate supply | LED pins tied to independent 12V; switch controls other voltage | Galvanic separation between indication and circuit |

Industrial Applications and Use Cases
A YJ-GQ16/19/22 Colorable metal button 22mm metal push button switch with a 12V LED is not just for hobby projects; it shows up in a wide range of B2B and OEM scenarios. This is why buyers and engineers care about long‑term reliability, contact plating, and panel sealing.
Where These Switches Are Commonly Used
- Industrial control panels and machinery HMIs
- Transportation, automotive, and marine
- Public terminals and kiosk equipment
- Power supplies and inverters
If you are working on a new equipment design and need to standardize on one 22mm metal push button platform across multiple models, you can ask suppliers for a full range including momentary, latching, emergency stop, and indicator versions with similar mechanical design.

FAQ
Momentary switches spring back when released and are used for signals like start or reset, while latching switches stay in position and act as on/off controls.
Only if the LED and contacts are rated appropriately; many series offer 6V, 12V, and 24V LED versions, so the LED’s rated voltage must match your system supply.
Datasheets and product markings typically label COM, NO, NC, LED+, and LED−, and correct identification is essential before wiring to avoid damage.
Many 22mm metal models provide IP65 or IP67 front protection, making them suitable for outdoor panels, vehicles, and washdown environments when installed correctly.
Yes, many manufacturers support custom legends, symbols, and LED colors on 22mm metal push buttons, especially in anti‑vandal ranges.
