Product Information
Full details
This round black rocker switch from Switch Electronics is designed for users needing a reliable SPDT (Single Pole Double Throw) switch with an 'on-on' action for momentary or maintained circuit control. Its snap-in mounting and standard 20mm panel cut-out make it easy to integrate into various projects. A key benefit is its versatile application across electronic devices and control panels, though users should note its specific current and voltage ratings to ensure compatibility with their systems.

FAQs
What does SPDT mean?
SPDT stands for Single Pole Double Throw. It means the switch has one input terminal (the pole) and can connect that input to one of two output terminals (the throws), allowing you to switch between two different circuits.
What is the 'on-on' action?
An 'on-on' action means that in each position of the rocker, the circuit is completed. Unlike momentary switches which only make contact while pressed, both positions of this switch are stable and maintain a circuit connection.
What size hole do I need to mount this switch?
You will need a panel cut-out that is precisely 20mm in diameter for the snap-in mounting mechanism to work correctly.
Can this switch be used for DC circuits?
While rated for 250VAC, it can typically be used for DC circuits at lower voltages and currents. However, always ensure the DC voltage and current do not exceed the switch's capabilities and consider the potential for arcing, especially at higher DC voltages.
What is the maximum current and voltage this switch can handle?
The switch has a maximum current rating of 6A and a maximum voltage rating of 250VAC.
How do I connect wires to the switch?
The switch features 4.8mm quick connect terminals. You will need compatible spade connectors to attach your wires securely to these terminals.
Troubleshooting
Switch does not change circuit state
Verify that the rocker is fully moving between its 'on' positions. Check wiring connections to ensure they are secure and correctly attached to the appropriate terminals for the desired circuit path. Ensure the load does not exceed the switch's current rating.
Switch is loose in the panel cutout
Confirm that the panel cut-out is precisely 20mm in diameter. Ensure the mounting tabs on the switch are engaging correctly with the panel material. If the panel material is too thin or flexible, additional mounting support may be required.
Overheating during operation
Immediately disconnect power. Check the connected load to ensure it does not exceed the switch's maximum current rating (6A). If the load is within limits, inspect wiring for loose connections or excessive resistance.
Pros and Cons
Pros
- Versatile 'on-on' functionality for dual circuit control.
- Simple snap-in mounting for quick installation.
- Standard 20mm panel cut-out ensures broad compatibility.
- Reliable SPDT contact configuration.
- Compact size for space-constrained applications.
Cons
- Limited current and voltage ratings (6A/250VAC) may not suit high-power applications.
- Not suitable for applications requiring momentary 'off' states.
- Requires precise panel cut-out size for secure fit.
Setup, Compatibility & Care
Setup: To install, ensure you have a panel with a precisely cut 20mm diameter hole. Align the switch's body with the cut-out and apply firm, even pressure until it snaps securely into place. Connect wires to the 4.8mm quick connect terminals, ensuring proper polarity and secure crimping. Double-check all connections before applying power.
Compatibility: This switch is compatible with panels that have a 20mm diameter mounting hole. It is designed for circuits with a maximum load of 6 Amperes and a maximum voltage of 250 Volts AC. Ensure your application's electrical requirements do not exceed these specifications.
Care: Keep the switch clean and free from dust and moisture. Wipe with a dry or slightly damp cloth as needed. Avoid using abrasive cleaners or solvents, as they can damage the plastic housing. Ensure electrical connections remain clean and corrosion-free.
