Need to install an external push button to arduino UNO

Hi everyone, I'm very new to the arduino world. I've just buyed an Arduino UNO and usb cable. The thing is I want a push button to be connected to the arduino, but I want this button to be big enough, like a joystick button, because the button that plugs to the breadboard is really small. Is there any choice not to use the classic button in the breadboard?? I haven't found anything yet... Thanks a lot!

Mike
