Year of discovery 2005

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, with a recovery time of 256 ticks.

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 to construct a "bobsled" oscillator in June 2005, in which a switch engine factory sends switch engines down a channel, at the other end of which they are deleted.[1][2][3] Since then signal circuitry related to switch engines have been investigated.[4] 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[5] that do not use an intermediate switch engine channel.

In 2021 wwei23 discovered that a claw with tail can replace the boat catalyst in a non-trivial way,[6] suppressing a large trailing spark and potentially reducing the repeat time of the switch engine channel from 256 ticks down to 144.[7]
