A switch engine channel is a conduit consisting of two lines of boats (or other suitable catalysts, such as tub with tails) arranged so that a switch engine can travel between them.
Technically the smallest unit of repetition is a single boat, producing a glide-reflected switch engine. However, very few conduits are known with input or output switch engines, and for most purposes it is more convenient to combine two of the elementary conduits to make a simple diagonal channel.
David Bell used this in June 2005 to construct a "bobsled" oscillator, in which a switch engine factory sends switch engines down a channel, at the other end of which they are deleted. In 2009 Adam P. Goucher used the mechanism to construct the first complete glider-to-Cordership converter, though much more compact converters have been completed since then[1] that do not use an intermediate switch engine channel.
