## Summary description

Kabelmeister JW40-020MM-3 jumper wire set includes 3 pieces of multicolour solid tip wires, each 20 cm long. Designed for breadboard use, these wires ensure reliable connections for your electronic projects.

## Long description

The Kabelmeister JW40-020MM-3 jumper wire set contains three 20 cm solid-tip jumper wires in multicolour insulation, designed for breadboard and prototype circuit connections. Each wire uses a solid conductor and male-to-male solid tips for straightforward insertion into standard 2.54 mm pitch breadboards and header pins. The compact set is intended to support simple wiring tasks during prototyping, learning and small repair or testing operations.
Advantages
Solid-tip conductors provide stable contact in solderless breadboards and reduce the risk of bent or frayed wires compared with stranded leads. The 20 cm length offers enough reach for typical breadboard layouts while remaining easy to route on a workbench. Multicolour insulation helps visually separate signals and simplifies tracing and debugging during assembly and testing.
Suitable for
Breadboard prototyping and circuit assembly
Connecting modules, sensors and microcontroller headers
Educational electronics projects and lab demonstrations
Quick testing and temporary wiring in repairs
Key specifications
Conductor type: solid (single-core) wire
Connector ends: male solid tip to male solid tip (suitable for 2.54 mm pitch)
Length per wire: 20 cm
Quantity: 3 pieces
Insulation colour: multicolour
How to use
Select wires of the needed colours and insert the solid tips directly into breadboard holes or female headers on development boards. Ensure the wire is fully seated for reliable contact and avoid excessive bending at the insertion point to maintain conductor integrity. For repeated use, check tips for deformation and replace any wire that shows wear or damage to avoid intermittent connections.
Usage recommendations
For organized layouts, assign consistent colours to power, ground and signal lines. When working with multiple wires, route them along the breadboard rows and secure bundles with temporary ties to reduce accidental disconnection and make debugging easier.
