Google should be able to give you the info on how to connect a switch to a serial port.
A search of CPAN for SerialPort gives 25 results but not all are applicable. Look at Device::SerialPort, Win32::SerialPort, Win32API::CommPort or perhaps even X10.
I wish that I had time to play\Wwork with this sort of stuff.
Update: Fixed my http://search.cpan.org url.
