FASTON terminals or faston terminals are connectors that are widely used in electronic and electrical equipment. These terminals are manufactured by many companies, commonly using the terms "quick disconnect", "quick connect", "tab" terminals, "spade" terminals^[1] or blade connectors; without qualifiers, the first two could be mistaken for plumbing connections.^[2]

The terminals are often called "quick disconnect" because the predecessors were screw terminals, which took longer to disconnect. The name "tab" terminals is a description of the shape of the male terminal.

Six series are covered in one of TE's catalogs (which omits the 0.375 in/9.5 mm, but mentions it elsewhere), named after their blade width in mils.^[3] Insulated versions of the terminals are color-coded to indicate what wire gauges they may be used with. The terminal system consists of tabs (male) and receptacles (female). There are free-hanging wire and circuit board mounted versions of both tabs and receptacles. All widths come mostly in one of two tab thicknesses: 0.032 and 0.020 in (0.8 and 0.5 mm).

A hand tool exists for inserting the terminals: the AMP Universal Handle.^{[citation needed]}

They have been commonly used since the 1970s. Faston is a trademark.

Four main styles of crimps are specified by AMP:

• "F" Crimp for use on non-insulated connectors
• TETRA-CRIMP for use on insulated PIDG and PLASTI-GRIP connectors
• "C" Crimp, typically used for flag connectors (where the wire enters the connector perpendicular to the direction of tab insertion)
• Tab-Lok, typically used for flag connectors

The colors are not for signal or polarity identification, but specify their compatible wire size range in AWG (or equivalent metric cross-sectional area):
