A push button starter SWITCH has become a popular modification for vehicles, machinery, boats, lawn equipment, and various electrical devices. Instead of turning a traditional key or Toggle Switch, users simply press a Push Button Switch to activate the starter or power circuit. This offers improved convenience, faster activation, and a modern appearance—especially when using an illuminated push button switch.
Whether you're upgrading a car to a modern start system or wiring industrial equipment, understanding how a push button switch works and learning how to wire a push button start switch safely is essential.
1. What Is a Push Button Starter Switch?
A push button starter switch is a manually operated electrical component designed to momentarily energize a starter circuit. When you press the button, it sends a signal to the starter relay or solenoid, causing the engine or device to activate.
It is essentially a push button switch built to handle ignition or start signals. Many users upgrade from traditional key switches to a more modern button switch, especially in custom automotive builds.
Types of push button switches:
Momentary push button switch (most used for starters)
Latch-type push button on off switch
Illuminated push button switch
Waterproof metal push button switch
Anti-vandal stainless steel push button switch
Momentary switches are preferred for starting because they only send power while being pressed.
2. How Does a Push Button Switch Work?
To understand installation, you must first know how does push button switch work. Inside the switch, there are movable and fixed metal contacts. When you press the button:
The contacts touch each other.
A complete circuit is formed.
Electrical current flows to the starter relay.
Releasing the button breaks the circuit again.
This simple mechanism explains how a push button switch works—a momentary contact system that only activates while pressed. It is safe, controlled, and prevents damage from long cranking.
3. Tools and Materials Needed
Before installing the push button starter switch, prepare these basics:
Tools:
Screwdrivers
Wire stripper
Pliers
Electrical tape
Drill (if dashboard installation is required)
Materials:
The chosen push button switch
Automotive-grade wires
Fuse (3–10A depending on system)
Relay (if the load requires it)
CONNECTORs and terminals
Make sure the button switch you purchase is suitable for automotive or machinery use.
4. Safety Precautions
Electrical modifications require proper handling, especially in vehicles.
Always disconnect the negative battery terminal.
Avoid working near fuel lines or flammable liquids.
Keep wiring organized and insulated.
Follow recommended fuse ratings.
Never bypass factory safety systems without understanding the risks.
Safety comes first when working with ignition circuits.
5. How to Install a Push Button Starter Switch (Step-by-Step Guide)
The following guide illustrates the installation process for vehicles and machinery. The concepts apply to most starter systems.
Step 1: Disconnect the Battery
Before touching any wiring, disconnect the negative battery terminal. This eliminates the risk of shorts or accidental cranking.
Step 2: Select a Mounting Location
Choose a place that is:
Easy to reach
Protected from water
Away from sharp edges or heat sources
If your push button starter switch is illuminated, choose a location where the light is visible for convenience.
Step 3: Identify the Starter Trigger Wire
The starter trigger wire is the small wire on the starter solenoid or relay. It carries a low current signal that commands the starter motor to turn.
You will connect your push button on off switch to this trigger circuit.
Step 4: Provide a Power Source for the Button
You can source power from:
The ignition switch “ON” position
A 12V accessory circuit
A separate fused power line
This ensures the button only works when the ignition is switched on, adding safety.
Step 5: Connect the Push Button Starter Switch
Here is the general wiring logic explained without code and without diagrams, using clear language:
One terminal of the push button switch is connected to a fused 12V ignition power wire.
The other terminal is connected to the starter solenoid’s trigger wire.
For an illuminated push button switch, the LED terminals connect to:
A positive ignition wire
A clean ground point
Pressing the button sends current to the starter relay, and the engine cranks.
Step 6: Test the Switch
Reconnect the battery and test the system.
Switch ignition ON
Press the push button starter switch
The engine or device should start
The illuminated light (if included) should function normally
If the starter engages continuously, immediately stop and check wiring.
Step 7: Final Wiring Protection
Once testing is successful:
Wrap exposed wires with insulation tape
Secure wires using zip ties
Ensure no wires touch hot surfaces
Confirm the button fits firmly in the mounting hole
A clean installation ensures long-term reliability.

10. FAQ (Frequently Asked Questions)
1. How does push button switch work?
It activates a circuit when pressed, sending power to the starter relay. Once released, the circuit opens again.
2. Can I install a push button starter switch myself?
Yes, if you understand basic electrical wiring and follow safety steps.
3. Do I need to keep the existing ignition key?
Yes. Most users still need a key to turn ON the ignition for safety.
4. Does the switch need a fuse?
Absolutely. A fuse protects the circuit from overload or short circuits.
5. What is the difference between momentary and latching push button switches?
Momentary: Only works while held down (for starters)
Latching: Stays on until pressed again (not recommended for starter systems)
6. Can an illuminated push button switch drain the battery?
No, if wired correctly to ignition power.
