Manual Switch

How do i set up a pulse input for a 555 chip from a power source with no manual switch.?

I have a 555 chip that i want to set up to count down 10min and i have a relay that when activated sends power to the chip but my basic understanding is that the input signal must be less than the output (in the length of the input signal). How do i convert the input signal from a continuous signal to a single pulse?? Does this Make sense??

One way is to use a momentary switch, like a push button. It doesn't stay on, it goes back to it's off positon when you let go of it. This would trigger the timer without being longer than the output. Another way is to put a capacitor in series with the switch. This would cause a pulse when the switch is turned on that would start the timer.
