2007 won’t start

[Susan]

I love this car. It’s a 2007 Sportage manual transmission with 180k on it. It has decided not to start recently (nothing when ignition is turned) and I suspect the clutch security switch. It will start when you pump the clutch to the floor a couple of times. Before replacing the switch, could the problem be the contact piece that pushes against the pin of the switch? It appears to be missing. Any advice would be greatly appeciated
