Single Pole Double Throw switch.

SPDTs are great for selecting between two power sources, swapping inputs, or whatever it is you do with two circuits trying to go one place.

• ON/ON 
• 6A 125V AC
• 3A 250V AC
• Connects a common terminal (C) to one or the other of two terminals (A & B).
• It is always connected on one or the other.
• The two outside terminals are never connected by the switch.

You can also use this as a Single Pole Single Throw (SPST) switch by just using the common terminal (middle one) and either of the outside terminals.
