What is a formal alternative to verb 'toggle'?

For a long time I've been using a word 'toggle' to express change of states (normally button). Now I found out on Dictionary.com / toggle that toggle has such meaning in an informal language as a verb. Which would be the correct word to express verb for 'change state'?


Dictionary.com is misleading here. Toggle is the correct technical term. Perhaps they mean it is "informal' to use this technical term in a non-technical context.
