Set of 2 Mini 12V/24V Momentary Push Buttons — Pre-wired for Quick Surface Mounting
This set of 2 mini push buttons is the ideal solution for any electrical installation requiring precise, temporary control at 12V or 24V DC. Designed for surface mounting and supplied pre-wired, these buttons eliminate the need for drilling holes, making installation straightforward for automotive, motorcycle, marine, or DIY electronics projects.
Note: These are ‘momentary’ switches — the circuit remains active only while the button is pressed. For loads exceeding 0.5A, we recommend using an intermediate relay.
Why choose this model? (Key Benefits):
- Drill-free installation: The double-sided adhesive backing allows for instant mounting on any clean surface without special tools.
- Error-free wiring: Pre-wired leads are colour-coded (red for ‘+’, black for ‘–’) for clear polarity identification.
- Instant response: The momentary function provides precise control for horns, indicators, or circuit testing.
- Dual compatibility: Works seamlessly with 12V systems (cars/motorcycles) and 24V systems (trucks, marine, industrial).
- Twin pack: Includes 2 pieces, perfect for symmetrical installations or as a spare.
Performance and Specifications
The construction features a durable plastic housing with a metal actuator for long-lasting reliability and satisfying tactile feedback. With a 0.5A current rating, they are perfect for signal circuits, logic inputs, or triggering relay coils. The approx. 30 cm cable length provides ample flexibility for a discreet installation, allowing wires to be tucked away behind dashboards or control panels.

Installation and Usage Instructions
- Thoroughly clean and degrease the surface where you intend to mount the button.
- Peel off the protective film from the adhesive backing and press the button firmly into position for several seconds.
- Connect the red wire to the positive (+) pole of your circuit and the black wire to the negative (–) or ground.
- Test the operation: the circuit should be active ONLY while the button is held down and cut off upon release.
- Properly insulate all connections using heat-shrink tubing or electrical tape to prevent short circuits.

Frequently Asked Questions
Do these buttons work on 24V, or just 12V?
Yes, these buttons are designed to operate reliably on both 12V DC systems (cars, motorcycles) and 24V DC systems (trucks, marine vessels, and industrial equipment).
What does ‘momentary’ mean?
It means the button completes the circuit only while you are pressing it. As soon as you release the button, the contact opens and the circuit is interrupted. This is ideal for horns, indicators, or temporary activations.
Can I use the button directly to power a high-draw LED or a motor?
Only if the total current draw does not exceed 0.5A. For larger loads (headlights, motors, compressors), we recommend using the button to trigger an automotive relay, which then switches the main load.
Is the adhesive backing resistant to vibrations and temperature changes?
The adhesive is sufficiently strong for interior use. For mounting in areas subject to extreme vibrations or high temperatures, we recommend supplementing with contact adhesive or mechanical fixing.
How do I correctly identify the wire polarity?
The red wire connects to positive (+), and the black wire connects to negative (–) or ground. Since the contact is purely mechanical, reversing the wires will not damage the button, but following the correct polarity is essential for the circuit being controlled.
