Claim 0:
1. A switching network, comprising:
a plurality of switches that each comprise a respective first side and a respective second side;
a catheter connector comprising a first set of connections and a second set of connections;
a three-dimensional (3D) mapping connector;
a recorder connector;
a control input;
an electrical switching circuit;
a patch connector;
one or more signal delivery connectors chosen from the group of: an ablation connector and a stimulator connector, wherein each of the one or more signal delivery connectors comprises a signal delivery connection and a return connection; and wherein:
the catheter connector and the 3D mapping connector are configured to couple a 3D mapping system to a first set of catheter electrodes through the first set of connections;
the patch connector and the one or more signal delivery connectors are configured to couple a patch electrode to a return of each of the one or more signal delivery connectors through the return connection of each of the one or more signal delivery connectors;
the catheter connector, the recorder connector, and the plurality of switches are configured to couple a recorder system, a second set of catheter electrodes, and the first side of each switch of the plurality of switches to a set of nodes, the second set of catheter electrodes being connected to the set of nodes through the second set of catheter connections, wherein a first node of the set of nodes is coupled to a first catheter connection of the second set of catheter connections, the first side of a first switch of the plurality of switches, and a first recorder connection of the recorder connector;
the plurality of switches and the one or more signal delivery connectors are configured to couple one or more signal delivery systems to the second side of each of the switches through the signal delivery connections, wherein the one or more signal delivery systems are chosen, based on the one or more signal delivery connectors, from the group of: an ablation generator and a stimulator; and
the control input and the switches are configured to couple a control input signal to the switches through the electrical switching circuit, wherein the electrical switching circuit is configured to:
in response to the control input signal indicating to close first one or more switches of the plurality of switches, couple the first side to the second side for each switch of the first one or more switches; and
in response to the control input signal indicating to open second one or more switches of the plurality of switches, decouple the first side from the second side for each switch of the second one or more switches;

a first filter switch coupled to a primary ablation node of the set of nodes; and
a second filter switch coupled to a primary ablation connection of the recorder connector;
wherein the control input, the first filter switch, and the second filter switch are configured to couple a filtering control input signal to the first filter switch and the second filter switch through the electrical switching circuit, wherein the electrical switching circuit is further configured to:
in response to the filtering control input signal indicating a first state, switch the first filter switch and the second filter switch into the first state, the first state configured to couple the first filter switch to a first connection of an RF prefilter and the second filter switch to a second connection of the RF prefilter; and
in response to the filtering control input signal indicating a second state, switch the first filter switch and the second filter switch into the second state, the second state configured to:
decouple the RF prefilter from the primary ablation node and the primary ablation connection; and

couple the first filter switch to the second filter switch.
