is it possible to burn out the starter

[oLemurs]

what im saying is when i tried to start my car after it sitting for a while it wont even turn over, i have everything bypassed so i push a button and it starts so essentially when i flip the starter signal wire it will turn on even without a key in the ignition but heres where i possibly messed up. i put a screw behind my switch panel to hold it in but im thinking the switch possibly jumped the two connectors together and eventually burnt it out. i did see some weird smoke coming from near the intake manifold and im just wondering what would happen if i were to just hold down the starter for about a minute or two.
