The glider-producing switch engine (or glider-making switch engine) is a puffer that was found by Charles Corderman in the early 1970s. It consists of a switch engine reacting with blocks to produce various still lifes, several blinkers, and a glider every 384 generations.

It is the second most common naturally-occurring pattern that exhibits infinite growth, the most common being the block-laying switch engine.

Because of its easy construction (see its predecessors below), it has appeared in some superlinear growth patterns including mosquito 3.[1]

Time bomb

The time bomb (shown below) is a 17-cell pattern that was found by Doug Petrie that evolves into a glider-producing switch engine.[2]

Synthesis

Although clean synthesis of glider-producing switch engine requires 5 gliders, Michael Simkin has found very messy 3 gliders synthesis in 2014[3]. This is the only known three glider synthesis of any infinite growth pattern, and it has the minimal number of gliders possible for infinite growth.
