1. A system, the system comprising:
a treatment applicator, the treatment applicator comprising a plurality of electrodes, and a plurality of treatment applicator electrical connectors in communication with the plurality of electrodes;
a pulse generator configured to deliver microsecond or sub-microsecond pulses having a voltage of 1 kV or greater, wherein the pulse generator is configured to engage with the plurality of treatment applicator electrical connectors so that the plurality of electrodes are in electrical communication with the pulse generator;
a plurality of impedance matching circuits; and
an impedance matching selector configured to selectively couple the plurality of treatment applicator electrical connectors with one or more of the plurality of impedance matching circuits based on an encoding shape connection with the plurality of electrodes to connect the treatment applicator to the pulse generator, wherein the impedance matching selector comprises a first set of internal electrical contacts comprising high-current/high power contacts separated from a second set of internal electrical contacts by a minimum clearance distance that avoids arcing and wherein the first set of internal electrical contacts is configured to couple with the second set of internal contacts to engage one or more of the plurality of impedance matching circuits when the encoding shape connection connects with the treatment applicator.
