A switch engine (or Corder engine[1]) is a methuselah found by Charles Corderman in 1971. It is unstable by itself, but it can be used to make c/12 diagonal puffers and spaceships.

There are two basic types of stabilized switch engine, both of which were also found by Charles Corderman: the period 288 block-laying switch engine (the more common of the two) and period 384 glider-producing switch engine. These two puffers are the most natural infinite growth patterns in Life, being the only ones ever seen to occur from random starting patterns.

Stable pattern

The stable pattern that results from the switch engine has 842 cells.
