Yes, it will work but you will bypass safety features inherent in the stock system.
A relay would be a good idea, since the pump may pull enough power to overload the switch.
In a stock setup, when you first turn the key on, a fuel pump relay runs the pump for a couple of seconds to pressurize the system for start-up. After that, the fuel pump won't run until there's oil pressure.
That way, if you lose oil pressure (low oil or car is upside down via a rollover) the fuel pump will shut off.
With a switch, it's on all the time and in an accident it will run fuel out if there is a broken fuel line. Can be risky.
