The flint for the gas fire in my camping car is broken - any ideas on repairs?

I am staying in my camping car in a ski resort and suddenly the flint for the old but efficient gas fire has broken. It is a round button that one pushes to make a loud click and I think this sends a small electrical current down to light the pilot. As the town supply of electricity to us campers is on the blink right now I am desperate to get this fixed ! There is no loud click, something has let go inside the button. I have taken the “button” out and see it is attached to a thin electrical wire which detaches with a small “plug”. Is there any other way of getting the necessary “click” down the wire to the pilot ? Thjankyou in advance bbrrrrrr!
