• Smart Home Hardware: Build elegant wall-mounted control nodes or mechanical access-control overrides that interface easily with low-voltage logic.

Project Evolution

• If you have spent your past development cycles mastering basic, fragile plastic tactile breadboard buttons or flimsy plastic toggles, upgrading to this 16mm metal push button completely transforms your design workflow. Flimsy buttons limit your projects to indoor benchtop environments and introduce frustrating contact bounce issues.
• This ProMax industrial switch unlocks the ability to deploy your projects safely into the real world—shielding internal electronics from rain, dust, and heavy manual handling. The integration of a pre-tested cable assembly eliminates field connection failures entirely.
• Effort Level: Intermediate (Requires basic panel cutting and low-voltage logic interfacing)
• Minimum Hardware Needed: 16mm panel punch/drill, a 5V or 6V DC power rail, and a compatible micro-controller setup or relay board.

Virtual Technician & Wiring Guide

• The pre-installed 3-pin JST connector simplifies your installation. The built-in protection resistor ensures that the internal illumination circuit acts as a Probots™ Logic-Safe ????️ layout when powered from regular low-voltage rails.
• Pin 1 (Red Wire): LED Positive (+) Anode Input (6V DC Nominal; safe for 5V logic rails at slightly reduced brightness)
• Pin 2 (White Wire): Switch Contact A (Common Terminal)
• Pin 3 (Black Wire): Switch Contact B (Normally Open Terminal) / LED Ground (-) Cathode Shared Common
• Safety Warning: Do not apply 12V or 24V directly to the Red LED pin without an external current-limiting resistor, as doing so will permanently blow out the internal green LED assembly.

Frequently Asked Questions (FAQ)

1. What is the mounting hole diameter for this metal push button switch?
   This switch requires a standard 16mm cutout hole on your panel or enclosure plate for proper installation.
2. Is this switch momentary or latching?
   This is a latching (self-locking) switch. When pushed down, it stays mechanically locked in the ON position until pushed a second time to release it back to OFF.
3. What is the rated voltage for the green LED backlight?
   The integrated green LED power symbol is factory-rated for optimal illumination at 6V DC.
4. Can I run the LED on 5V from an Arduino or Raspberry Pi?
   Yes, the LED illuminates perfectly when powered from a standard 5V logic rail, running slightly dimmer while remaining highly visible.
5. What type of cable connector is pre-installed on this switch?
   The switch comes pre-terminated with a standard 3-pin JST female connector, eliminating any need for soldering.
6. What is the exact length of the integrated wire harness?
   The integrated premium-insulated wire harness measures exactly 300mm (30 centimeters / approximately 12 inches) in length.
7. What is the maximum current rating for the switch contacts?
   The heavy-duty internal silver alloy contacts are safely rated to switch loads up to 3A at 250V AC or 5A at 30V DC.
8. Is this illuminated switch fully waterproof?
   Yes, the front panel face has an IP67 rating, meaning it is entirely dust-tight and fully protected against water ingress during rain or heavy spraying when mounted with the included O-ring.
9. What material is the outer shell body made of?
   The outer structure is machined out of heavy-duty, premium nickel-plated brass to provide long-term corrosion and impact resistance.
10. How do I wire the LED power symbol?
    Connect positive voltage (5V–6V) to the Red wire and ground to the Black wire to illuminate the icon, routing your main signal circuit through the White and Black wires.
11. Does the LED turn on only when pressed or can it stay on constantly?
    It can be wired both ways. If the LED positive line is tied to your system power rail, it stays on constantly; if routed through the switch contact itself, it turns on only when active.
12. Does it require soldering to install?
    No soldering is required. The integrated wire harness provides a secure, vibration-resistant plug-and-play connection point out of the box.
13. Can I use this push button for a 12V automotive application?
    Yes, but you must add a 330-ohm to 470-ohm series resistor onto the Red wire line to drop the voltage safely from 12V to avoid burning out the 6V LED.
14. What are the three pin functions on the JST connector?
    The pins provide positive LED power (Red), main switch input contact (White), and a combined return ground path for the switch/LED (Black).
15. What JST pitch size is used on the connector terminal?
    The connector utilizes a standard 2.54mm pitch spacing layout common across standard robotics control boards and development shields.
16. Why is my LED not lighting up when the switch is toggled?
    LEDs are directional components. Verify that the positive power supply wire is running into the Red wire pin and your ground is connected to the Black wire.
17. What is the difference between this latching switch and a momentary switch?
    Latching switches act like a standard light switch (click on, click off), whereas momentary switches act like a keyboard key (only active as long as your finger physically holds it down).
18. Can this switch be used to power a heavy DC motor directly?
    If your DC motor draws a continuous or startup current over 3A, you must route this switch to a relay module or MOSFET driver rather than driving the motor directly.
19. Does this switch have a normally closed contact option?
    To preserve a compact footprint and simple plug-and-play wiring, this 3-pin version is pre-wired exclusively for Normally Open (NO) switching configurations.
20. How do I clean or maintain the front panel faceplate?
    Because the front assembly is IP67 sealed, you can easily wipe down grime, grease, or dust using a damp fiber cloth without risking damage to the internal electronics.
