Disclosed is an apparatus for optimally facilitating interconnections between electrical endpoints. The apparatus comprises a number of terminals equal to a number of combinations of the plurality of endpoints. For example, to enable combinations of two endpoints to be made between N endpoints, the apparatus comprises N(N1)/2 terminals. Each terminal at least comprises a first contact coupled to a first endpoint and a second contact coupled to a second endpoint. The first contact and second contact of any terminal can be shorted to connect their corresponding endpoints. The apparatus may further comprise a circuit identification process executed by a microcontroller. In this case, each terminal additionally comprises a first circuit identification contact and a second circuit identification contact. The process involves outputting a voltage to the first circuit identification contact and detecting the voltage of the second circuit identification contact to determine whether the corresponding terminal is activated.
