	The '''selector combinator''' is part of the [[circuit network]] and one of four types of combinators available in the game (the other three being the [[constant combinator]], [[arithmetic combinator]] and [[decider combinator]]). It has ~~four~~ different modes of operation (or ~~seven~~ with [[Space Age]]{{SA}} enabled) to filter out various signals from an input wire.		The '''selector combinator''' is part of the [[circuit network]] and one of four types of combinators available in the game (the other three being the [[constant combinator]], [[arithmetic combinator]] and [[decider combinator]]).
