Flip‐flop: Mechanical and opto‐mechanical switching cycle of a nanoswitch made up of single dithioazobenzene chromophore suspended between two gold tips (see picture). Mechanical switching proceeds on the ground‐state S 0 surface while successful optical switching via S 1 state requires mechanical assistance.
