ABSTRACT:
A patch or access module usable with an insertable patch plug having a plurality of electrical contact elements. The patch or access module includes a circuit board, a first electrical circuit electrically connected with a first point on the circuit board, a second electrical circuit electrically connected with the second point on the circuit board and switch contact means for selectively making electrical connection between the first point and the second point and for making electrical connection between the first point and the electrical contact elements of the patch plug upon insertion of the patch plug into the patch or access module. The switch contact mechanism includes a first portion electrically engaged with the first point, a second portion adapted for selective electrical engagement with the second point and a third portion adapted for limited movement relative to the circuit board for electrical engagement with the electrical contact element of the patch plug when the plug is inserted into the patch module.
