Next, bend the wire into a pig tail loop so that you can easily attach. (Those wires are stripped back a little too much. you can lay one wire on each side of the screw under the clamp. The wire strippers should have a spot marked for each gauge wire. The most universal answer is to get a +/-4' piece of solid wire (not white, green or gray) to connect to the new switch, then connect that wire and the two reds together with a properly sized wire connector. Use the voltage tester to confirm that power has been disconnected. Then, use your wire strippers and strip away about 5/8 of an inch of the insulation from the wire. You must disconnect the power from the switch wires. They are typically connected using 14/3 gauge electrical wire. It is also possible to wire your switches using INPUT mode, not INPUTPULLUP, and have them read LOW when the switch is. Flip the switch the other way and it would connect the other pin to ground, at that other pin would drop from HIGH to LOW. A switch provides a mechanical method for opening and closing a circuit. That would connect that Arduino pin to ground, and the reading on the pin would drop from HIGH to LOW.
