Abstract

A member has two (2) spring arms each movable between first and second positions. Each spring arm is normally biased to a first position and is movable to a second position. Each spring arm has at its free end an insulator and a conductor disposed on the insulator. The insulator isolates the conductor electrically from the associated spring arm. An electrical lead is connected between the conductors. In the first position of the spring arms, the electrical conductors engage individual ones of a pair of probes and establish common probe potentials. Each probe is disposed coaxially in an insulator in an individual one of a pair of electrical connectors and the insulator is disposed coaxially in a casing in the connector. The probe extends axially beyond the insulator and the casing in each connector so that the associated electrical conductor is able to engage the probe in that connector in the first position of the spring arm. This causes the two (2) connectors to be connected in series in this first relationship. When the spring arm associated with an individual one of the connectors is moved to a second position, the electrical conductor engages a first terminal in an impedance (e.g. a resistor) having a second terminal common with the connector casings to establish a reference potential (e.g. ground). In this second relationship, the electrical connector forms a circuit which includes the moved conductor, the impedance and the casing ground.
