Yep the connectors shown should work. They connect exactly like your current switches there are two sets of pins connected together (giving you two connections) one goes to ground and the other to the terminal of the Arduino just like the switches on the breadboard. If you solder wires to one of them you can connect it in place of a switch on the breadboard to test it. As noted you will need to change the software to change the programs sense of when the switch is active to make them work the same.
