When you need to switch a lot of power, P channel MOSFETs are best for the job. These P-FETs can switch over 60V and 25A (with proper heat-sinking) and are TO-220 package so they fit nicely into any breadboard or perfboard. Heat sinking is easy with TO-220s, but because of the very low Rds(on) of down to 70 mOhms (depending on the Vgs - check the datasheet) you can...

The Adafruit Push-button Power Switch is a tidy little design that lets you control a DC power source using an everyday tactile button. The breakout uses a latching analog circuit that is triggered by a push of the button. Press once to turn on, then press again to turn off. The circuit uses a 3A P-FET to connect and disconnect the IN pin to the OUT pin. Works great...
