Description
The Mercury test lead set includes 10 colour-coded leads fitted with insulated 25mm crocodile clips at both ends, supplied as five matched pairs: two red, two black, two green, two yellow and two white. Each lead measures 500mm from clip to clip, giving a working length suited to circuit testing, prototyping and lab diagnostics without excess cable.
Designed for electronics hobbyists, education environments and service technicians, the colour-coding simplifies multi-point testing and helps trace signal paths on breadboards, PCBs and test benches. The soft plastic insulation on each crocodile clip prevents accidental shorts and protects component legs and test points from metal-to-metal damage during connection.
The flexible wire construction handles repeated flexing at the clip junctions without hardening or fracturing, and the spring-loaded clips grip securely on component legs, terminal blocks and PCB pads between 0.5mm and 3mm diameter. The 25mm clip size strikes a balance between jaw strength for secure contact and compact footprint for working in densely-populated circuits.
Specification
Frequently Asked
What colours are included?
The set includes five pairs: two red, two black, two green, two yellow and two white. This allows matched pairs for positive/negative connections and multi-channel testing with colour-coded reference.
What size connections do the clips grip?
The 25mm crocodile clips grip component legs, terminal blocks and test points between approximately 0.5mm and 3mm diameter. The spring-loaded jaws provide secure contact without crushing small-gauge wires or component legs.
Are these suitable for mains voltage work?
No. These test leads are designed for low-voltage electronics diagnostics, prototyping and educational use. They are not rated or insulated for mains voltage (230V AC) work and must not be used on live mains circuits.
Can the clips be replaced if damaged?
The clips are crimped onto the wire ends and are not designed to be user-replaceable. If a clip fails, the most practical solution is to replace the individual lead from the set.
