Product Information
Full details
The Switch Electronics 6.3mm Insulated Spade Crimp Connector Terminal 100-pack is designed for automotive enthusiasts, DIY electricians, and hobbyists who require reliable, secure terminations for 16-22 AWG wiring projects. These terminals provide a robust electrical connection and prevent short circuits through integrated insulation, making them ideal for quick-disconnect applications; however, users must possess a dedicated crimping tool to ensure a proper mechanical bond, as pliers are insufficient for professional-grade results.

Extended Product Information
FAQs
Are these connectors suitable for household 120V AC wiring?
No, these are designed for low-voltage DC applications (16-22 AWG) commonly found in automotive and electronics projects.
Can I use these for 14 AWG wire?
No, 14 AWG wire is too thick for these connectors. These are specifically sized for 16-22 AWG.
Do I need to solder these connections?
A proper mechanical crimp is sufficient for most applications. Soldering is optional but generally unnecessary if a professional-grade crimper is used.
What does the red color indicate?
In the electrical industry, red insulation indicates the connector is rated for 16-22 AWG wire.
Are these connectors weather-proof?
These terminals are insulated but not weather-sealed. For outdoor or under-hood use, add heat-shrink tubing for extra protection.
Troubleshooting
Connector slips off the wire after crimping
The wire gauge may be too small for the terminal or the crimp pressure was insufficient. Use a proper ratcheting crimper for 16-22 AWG.
Terminal is loose on the metal tab
Ensure the tab is a standard 6.3mm size. If the tab is undersized, the spade may need a gentle squeeze with pliers to increase tension.
Insulation cracks during installation
Ensure your crimping tool jaws match the insulated barrel size; using a non-insulated jaw profile will damage the protective coating.
Pros and Cons
Pros
- Industry-standard 6.3mm spade size for wide compatibility
- Insulated barrels enhance safety and reduce short-circuit risks
- Large 100-pack quantity is highly cost-effective for recurring projects
- Color-coded red insulation allows for quick wire gauge identification
Cons
- Requires a specific crimping tool for reliable performance
- Not intended for high-current applications exceeding standard low-voltage limits
- Insulation can be damaged if the wrong crimping jaw profile is used
Setup, Compatibility & Care
To use these terminals, strip approximately 6-8mm of insulation from your wire. Insert the bare wire into the metal barrel of the connector. Using a professional ratchet-style or manual crimping tool, apply firm pressure to the center of the insulated section. Avoid using needle-nose pliers, as they may crush the metal rather than creating a secure mechanical lock. For longevity, keep these connectors in a cool, dry environment. If used in a high-moisture environment like a car engine bay, consider applying a small amount of dielectric grease or using heat-shrink tubing over the joint to prevent corrosion.
