Dual contact pogo pin assembly

A connector comprising:

• a circuit board including a plurality of conductive pads arranged in pairs, each pair of pads comprising a first conductive pad and a second conductive pad;
• a housing secured to the circuit board and including a plurality of apertures;
• and
• a plurality of contact assemblies, each of the contact assemblies being positioned in one of the apertures of the housing and configured to shift within the housing, each of the contact assemblies being configured to engage one of the pairs of conductive pads, each of the contact assemblies including—
• a base formed at least partially of an electrically nonconductive material;
• a first electrical contact supported by the base and configured to engage a first conductive pad;
• a second electrical contact supported by the base and configured to engage a second conductive pad;
• the first contact and the second contact being electrically isolated from one another and configured to compress when engaging an external connector element,
• the base including an aperture positioned on an end of the base opposite the circuit board, the aperture being positioned outboard of the first and second electrical contacts and presenting a narrowing shape with a wide mouth distal the electrical contacts and a narrow internal through-hole proximate the electrical contacts.
