5. Setup and Installation

Proper installation is crucial for the functionality and safety of your switch. Follow these steps carefully:

5.1 Mounting the Switch

1. Choose a suitable location for the switch on your vehicle's dashboard or panel.
2. Drill a 19mm (0.75 inch) diameter hole at the chosen location. Ensure the hole is clean and free of burrs.
3. Insert the switch into the drilled hole. The switch is designed to sit snugly.
4. Secure the switch using the provided nut on the back side of the panel. Tighten firmly but do not overtighten.

5.2 Wiring the Switch

The switch has five terminals: three for the switch contacts (COM, NO, NC) and two for the LED light (LED+, LED-). Understanding these connections is key.

• COM (Common): This is the power input terminal for the switch function. Connect your positive power source to this terminal.
• NO (Normally Open): When the button is at rest (not pressed), there is no connection between COM and NO. When the button is pressed, the circuit between COM and NO is closed, allowing current to flow. Use this for functions that activate when the button is pressed (e.g., horn).
• NC (Normally Closed): When the button is at rest (not pressed), there is a connection between COM and NC. When the button is pressed, the circuit between COM and NC is opened, interrupting current flow. Use this for functions that are normally on and turn off when the button is pressed.
• LED+ (LED Positive): Connect the positive wire for the LED illumination to this terminal.
• LED- (LED Negative): Connect the negative (ground) wire for the LED illumination to this terminal.

Important Note on LED Wiring: To ensure the LED light is visible and functional, it is recommended to wire the LED independently from the switch's main function. For example, connect the LED positive to a circuit that is active when your vehicle's headlights or courtesy lights are on. This allows the LED to illuminate with your dash lights, making the switch visible without needing to press it. Connecting the LED directly to the switch's NO or NC terminals might only illuminate the LED when the button is pressed, which can be less practical.

Relay Requirement: For any electrical load exceeding 5 Amps, it is mandatory to use an automotive relay. The switch will then activate the relay, and the relay will handle the higher current load, protecting the switch from damage.

6. Operating Instructions

Once properly installed and wired, operating the ESUPPORT momentary switch is straightforward:

• To Activate: Press the button firmly. The switch will engage the connected circuit (e.g., sound the horn) as long as the button is held down.
• To Deactivate: Release the button. The switch will return to its original state, disengaging the circuit.

7. Maintenance

The ESUPPORT push button switch is designed for durability and requires minimal maintenance.

• Cleaning: Periodically wipe the visible surface of the switch with a soft, damp cloth to remove dust and grime. Avoid using abrasive cleaners or solvents.
• Connection Check: Occasionally inspect the wiring connections at the back of the switch to ensure they remain secure and free from corrosion.

8. Troubleshooting

If you encounter issues with your ESUPPORT switch, consider the following common problems and solutions:

• Switch Not Activating Connected Device:
  • Check all wiring connections for looseness or incorrect polarity.
  • Verify that the COM terminal is receiving power.
  • Ensure the correct output terminal (NO or NC) is used for your desired function.
  • Confirm that the connected device is functioning correctly and not drawing excessive current (requiring a relay).
• LED Light Not Illuminating:
  • Check the connections to the LED+ and LED- terminals. Ensure correct polarity (LED+ to positive, LED- to ground).
  • Verify that the LED circuit is receiving 12V power.
  • Ensure the LED is not damaged.
• Switch Feels Loose After Installation:
  • Tighten the mounting nut on the back of the switch.
  • Ensure the mounting hole is precisely 19mm; an oversized hole can cause looseness.
