Full details
This guide is for makers, hobbyists, and electronics enthusiasts looking for reliable single-pole, single-throw (SPST) switches. The key benefit is the straightforward on/off functionality for simple circuit control. A caveat is their specific amperage and voltage rating, requiring careful application. This pack contains 5 black, rectangular rocker switches from Switch Electronics, each with a panel cut-out size of 19 x 13mm and a rating of 6A 250VAC, suitable for basic switching applications.

FAQs
What does SPST mean?
SPST stands for Single-Pole, Single-Throw. It means the switch controls a single circuit and has two positions: ON (circuit closed) and OFF (circuit open).
What is the maximum current and voltage this switch can handle?
The switch is rated for a maximum of 6 Amps (A) at 250 Volts Alternating Current (VAC).
Can I use these switches for DC circuits?
Yes, you can use them for DC circuits as long as the voltage and current requirements of your DC device do not exceed the switch's rating (6A 250V). For DC, the voltage rating is often different than for AC, but for most common low-voltage DC applications, this switch should be suitable.
What is the panel cut-out size required?
The required panel cut-out size for each switch is 19mm x 13mm.
How are these switches wired?
These switches typically have two terminals. One terminal connects to the power source, and the other connects to the device you want to control. When the switch is ON, the circuit is complete; when OFF, it is broken.
Are these switches waterproof?
These switches are generally not rated as waterproof. They are intended for use in clean environments or within enclosures that provide protection from moisture.
Troubleshooting
Switch not turning device on/off
Verify power is connected to the switch. Check that the switch is correctly wired to the device and that the circuit is complete. Ensure the switch is rated for the current and voltage of your device.
Switch feels loose in the panel
Ensure the panel cut-out size is correct (19 x 13mm). The switch should have clips or a friction fit to hold it securely. If too loose, consider using a small amount of adhesive suitable for plastics or a gasket.
Intermittent connection
Check the wiring connections at the switch terminals for security and cleanliness. If the switch has seen heavy use or is overloaded, the internal contacts may be worn, requiring replacement.
Pros and Cons
Pros
- Simple and intuitive ON/OFF operation.
- Cost-effective for projects needing multiple switches.
- Standard size for easy integration into panels.
- Reliable brand manufacturing.
Cons
- Limited to basic SPST functionality (cannot switch between two different circuits).
- Specific voltage and amperage rating may not be suitable for high-power applications.
- Requires panel mounting; not suitable for free-hanging wire applications without modification.
Setup, Compatibility & Care
Setup: These rocker switches are designed for panel mounting. Ensure your panel has a rectangular cut-out measuring 19mm x 13mm. Insert the switch into the cut-out; it should snap or clip securely into place. Wire the terminals according to your circuit diagram. Typically, one terminal is for the input power, and the other is for the output to the device. Ensure power is disconnected before wiring.
Compatibility: These switches are compatible with 19x13mm panel openings. They are rated for 6A at 250VAC, so ensure your circuit's load does not exceed these limits. They are suitable for both DC and AC circuits within these ratings.
Care: To maintain performance, keep the switches clean and free from dust and debris. A dry or slightly damp cloth can be used for cleaning. Avoid using harsh chemicals or abrasive cleaners. Ensure the wiring connections remain secure and free from corrosion.
