It sounds like your switch is a three way switch. The wire that is on the different colour screw of the three screws will either be the "hot" wire or the wire to the load. The neutral might or might not be in the box that the switch is in depending on which end of the three way system you are at. See discuss question button below.

No wires connected to a switch are neutral. A switch breaks the circuit of the hot wire. Black AND red are hot wires. White is used for neutral and is almost never connected to a switch.

Can you change a light switch to toggle switch outlet?
You can if you have a neutral wire present. If the existing switch is what is called a "switch loop" then you can not change the existing switch to a switched outlet. You can identify a switch loop by looking at the wires coming into the switch bow. If there are only one set of wires usually a black and white and they go directly to the switch then you have a switch loop
How do you install a doorbell with four wires both having black and red wires?
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.
