Jumper wire Alcasa JW40-020MM solid tip for breadboard, 20 cm, multicolour, 1 pc

Alcasa JW40-020MM solid-tip jumper wire is a single 20 cm conductor intended for breadboard prototyping and short wiring tasks in electronics projects. The rigid solid tip provides stable insertion into standard breadboard sockets, while the multicolour insulation helps distinguish connections and simplifies circuit tracing during assembly and testing.

Advantages

The solid core offers reliable mechanical contact and maintains shape when inserted into a breadboard, reducing accidental disconnection. Its 20 cm length balances reach and neatness for most prototyping layouts. Multicolour insulation aids visual identification of signal paths and power rails, which speeds up debugging and reduces wiring errors.

Suitable for

• Breadboard prototyping and circuit assembly
• Connecting components and modules for quick testing
• Short low-current signal and power connections
• Educational electronics and hobbyist projects

Key specifications

• Conductor type: solid (single core)
• Length: 20 cm
• Tip style: rigid solid tip for breadboard insertion
• Insulation: multicolour PVC or similar insulating material
• Quantity: 1 piece

How to use

Insert the solid-tip end directly into breadboard sockets or component leads to establish connections. Route the insulated wire to avoid crossing over sensitive components and to keep the prototype layout clear. For reliable contact, ensure the breadboard holes are free of debris and that the wire is inserted fully until it seats firmly. Use different colours to represent distinct signals or power rails for easier identification.

Usage recommendations

Use the wire for low-current prototype connections only; avoid using solid core jumper wires where high flexibility or repeated flexing is required. For frequent reconfiguration, consider combining with flexible stranded jumpers. Store jumper wires untangled to preserve tip integrity and maintain consistent insertion performance.
