Understanding Push Button Switch Terminals
Connects when button is pressed
Always connected terminal
Disconnects when button is pressed
Step-by-Step Wiring Instructions
Identify the Circuit
Determine what device or system the push button will control. Common applications include:
- • Motor starters
- • Lighting circuits
- • Control panels
- • Emergency systems
Power Supply Connection
For 12V DC Systems:
- • Connect positive (+) to one side of the switch
- • Connect the load to the other side
- • Complete circuit through ground (-)
Switch Terminal Connections
Momentary Operation:
- • Use NO (Normally Open) terminals
- • Connect power source to COM terminal
- • Connect load to NO terminal
- • Circuit completes only when pressed
Latching Operation:
- • Requires additional relay circuit
- • Use auxiliary contacts for holding
- • Include stop button for release
- • Maintains state after release
Add Protection Circuitry
Fuse Protection
Install appropriate fuse rating between power source and switch to protect against overcurrent.
Relay Usage
Use relay for high-current loads to prevent switch damage and ensure reliable operation.
Testing and Verification
Use multimeter to verify continuity across switch terminals
Test operation with low voltage before connecting final load
Verify all connections are secure and properly insulated
Common Wiring Configurations
Simple On/Off Control
Basic momentary switch configuration for direct load control.
Start/Stop with Holding
Three-wire control with auxiliary contacts for motor control applications.
Goboll Quality Assurance
All Goboll push button switches are manufactured to meet international standards including UL, VDE, TUV, and CE certifications. Our switches undergo rigorous testing in our CNAS-accredited laboratory to ensure reliable performance and safety.
Troubleshooting Common Issues
Switch Not Responding
Check power supply, verify terminal connections, test switch continuity with multimeter.
Intermittent Operation
Inspect for loose connections, clean contact surfaces, verify proper wire gauge for current load.
Switch Stays Activated
Check for stuck mechanism, verify correct terminal usage (NO vs NC), inspect for short circuits.
