Key Applications

• Industrial Automation: Main power or mode selection for 24V PLC-based control panels.
  
• Marine & Marine Grade Panels: Waterproofing makes it ideal for boat dashboards and outdoor control boxes.
  
• Automotive/Trucking: Perfect for 24V auxiliary lighting, winches, or heavy-duty machinery overrides.
  
• Home Energy Systems: Ideal for manual control in 24V solar battery storage banks.

Project Evolution

• Prerequisites: If you have mastered 5V/12V logic circuits and are moving into industrial power standards (24V), this switch is your professional hardware bridge.
  
• Feature Upgrade: The 16mm 24V Metal Switch removes the need for voltage dividers or separate logic rails just for your indicator lights. It integrates directly with 24V industrial power supplies, simplifying your wiring and improving system stability.
  
• Effort Level: Intermediate. Working with 24V requires careful attention to wire gauge and insulation. We recommend using heat-shrink tubing on all 5 terminals to ensure a professional, short-circuit-proof finish.

Virtual Technician & Wiring
⚠️ SAFETY WARNING: While the switch can handle 240V AC on the contacts, the LED is rated for 24V DC ONLY. Connecting 240V to the LED pins will result in immediate failure.
Pin Mapping (Typical 5-Pin Layout):

• Pins "+" and "-": Green LED terminals (Connect to 24V DC).
• Pin "C" (Common): Your main input power.
• Pin "NO" (Normally Open): Connection to your load (Turns ON when button is pressed/latched).
• Pin "NC" (Normally Closed): Connection to your load (Turns OFF when button is pressed/latched).

Required

• 5-Pin Socket

Package Includes: 1x 16mm ProMax PPS16024GRL-11F  Metal Push Button Switch Waterproof Latching

Frequently Asked Questions (FAQ)

1. What does "Latching" mean?
   It means the button clicks into place and stays ON after you release it. You must press it again to turn it OFF.
2. Will the LED work on 12V?
   It will work, but the brightness will be significantly reduced. For 12V systems, we recommend our dedicated 12V LED variant.
3. Can I use this for a 240V AC load?
   Yes, the contacts are rated for AC, but the LED still requires a 24V DC supply.
4. Is the switch really waterproof?
   Yes, the front of the switch is IP67 rated, meaning it can handle rain and temporary immersion.
5. What size hole do I need?
   A standard 16mm diameter circular cutout is required.
6. Can I power the LED from a 24V PLC output?
   Yes, it is designed to be compatible with standard industrial 24V logic and power rails.
7. How do I make the LED stay ON regardless of the switch state?
   Wire the LED "+" and "-" pins directly to your 24V supply.
8. How do I make the LED light up only when the device is ON?
   Connect the LED "+" pin to the "NO" terminal of the switch.
9. What type of metal is the body?
   High-grade stainless steel or nickel-plated brass for maximum corrosion resistance.
10. Does it come with a gasket?
    Yes, a rubber O-ring is included to ensure a waterproof seal against your panel.
11. Can I use this for an Emergency Stop?
    While latching, it is not a mushroom-style E-stop. It should only be used for general power control.
12. What happens if I reverse the LED wires?
    Since it is DC, the LED will not light up if polarized incorrectly. Simply swap the wires.
13. What is the maximum current rating?
    It is typically rated for 3A to 5A depending on the specific batch; check the side of the switch for final verification.
14. Is the button flat or raised?
    This version features a slightly raised/high-round head for easy tactile discovery.
15. Can I use this in a car?
    Yes, it is excellent for 24V trucks and heavy machinery, but check your vehicle's voltage rail (12V vs 24V).
16. How deep is the switch?
    It requires approximately 35mm of clearance behind the panel.
17. What is the terminal type?
    2.8mm solder lugs, which can also accept small spade connectors.
18. Is the LED ring or the whole button illuminated?
    Only the outer ring is illuminated in Green.
19. Will it rust outdoors?
    No, the stainless steel construction is designed to resist rust and oxidation in outdoor environments.
20. Is there a 22mm version available?
    Yes, Probots carries a wide range of metal switches; browse the "Switches" category for larger sizes.
