Spade Connectors

Spade connectors create secure, removable push-on connections for appliances, automotive wiring, marine equipment, switches, relays, and control panels. Compare the terminal style, mating tab or stud size, wire gauge, and insulation type before choosing a heat shrink, nylon, open-barrel, or piggyback connector.

Applications

Appliances, HVAC controls, switches, relays, speakers, and equipment panels.
Automotive, trailer, marine, and outdoor circuits that may need future disconnection.
Use ring terminals instead for permanent battery-stud connections, and butt connectors for permanent inline wire splices.

How to Choose

Match the terminal barrel to the conductor AWG, not the cable jacket.
Choose male, female, fork, or piggyback style to match the mating connection.
Confirm the mating tab or stud dimension on the product page before ordering.
Select adhesive-lined heat shrink for moisture, salt, vibration, or outdoor exposure.

How to Use

Disconnect power, strip the wire to the barrel length, and avoid nicking strands.
Insert the conductor fully and crimp with the die specified for the terminal and AWG.
For heat-shrink models, heat evenly until the sleeve conforms and adhesive appears at the ends.
Allow the joint to cool, then tug-test and connect it to the matching tab or stud.

Spade Connector FAQ

How do I select the terminal type and AWG?

Choose the terminal style that matches the equipment connection, then match the terminal barrel to the stripped conductor gauge. Do not size the terminal from the outside diameter of the cable insulation. Use the color and AWG markings on the product page as the final reference.

Which male/female or stud size do I need?

Use a female quick-disconnect terminal on a matching male tab and a male terminal where the mating side is female. For fork or stud-style terminals, measure the screw or stud diameter and select the matching opening. Confirm the tab width and thickness or stud size before purchase.

When is heat-shrink insulation required?

Choose adhesive-lined heat-shrink insulation for marine, trailer, engine-bay, outdoor, or other moisture- and vibration-prone wiring. Standard nylon insulation is generally suitable for dry, protected interior connections when the application does not require a sealed joint.
