Abstract: An electrical connector post, preferably but not exclusively, for use in the construction of experimental electrical circuitry on a circuit board. In a preferred embodiment, the connector comprises two or more electrically conducting post sections having a through bore therein. Resilient means extends through the through bore of each of the conducting post sections and is secured at opposed ends to a respective securement element whereby to urge the post sections toward one another with the through bore of each post section in substantially axial alignment with one another. One of the securement elements is used to mount the connector post to a desired location.
