A multiplex electronic switch on the molecular level has been realized by using a tetranuclear Fe II complex of the [2×2] grid type. The four metal ions can be switched stepwise between their high‐spin and low‐spin states by temperature, pressure, and light, thus representing a triple level, triple switch system as illustrated in the picture.
