What device is used to ensure that a swaged terminal is correctly installed?

A go-no-go gauge is a precision tool designed to check if a particular item meets specified dimensions or tolerances. In the context of swaged terminals, this gauge is particularly useful for ensuring that the terminal has been properly swaged – or compressed – onto the wire. It consists of two parts: one that represents the acceptable dimension (the "go" side) and another that represents the unacceptable dimension (the "no-go" side).

When utilizing a go-no-go gauge, the technician can easily determine whether the swaged connection is within the acceptable limits. If the terminal fits the "go" side, it is deemed acceptable. If it fits the "no-go" side, it indicates that the terminal is improperly swaged and may require rework or replacement. This ensures safety, reliability, and consistent performance in applications where the integrity of the connection is critical.

In contrast, a caliper and a measuring tape are general measuring tools that may not provide the specific checks needed for this task. A torque wrench is used to apply a specific torque to bolts and fasteners, which is not relevant to the swaging process. Thus, the go-no-go gauge is uniquely suited for ensuring the correct installation of swaged terminals.
