It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.

It depends on whether your button is more than one block away from the entity you want to activate. If it is next to, say, a door, pressing the button will open the door without the use of redstone. If, however, you wish to distance the button from the door, then you will need a line of redstone connecting the button to the door.
