Tip: Conditions vs Switch, when to use each
Both let you branch your flow based on a value. The difference is how many branches you’re dealing with and how readable your flow stays once it’s built, or how readable it stays before you have to open it again in six months and wonder what past you was thinking.
WHEN TO USE A CONDITION
A Condition checks one thing and gives you two outcomes, yes or no, true or false. It’s the right tool when you’re checking something like whether a value is greater than zero, whether a field is empty, or whether two values match.
Conditions can be nested inside each other for more complex logic, but nest more than two or three deep and your flow turns into a choose your own adventure book nobody asked for. That’s usually the sign you’ve reached for the wrong tool.
WHEN TO USE A SWITCH
A Switch checks one value and lets you branch into as many outcomes as you need, each one running its own separate set of actions. It’s the right tool when you’re checking something like a status field, a record type, or a category, where there are several possible values and each one needs different handling.
Instead of nesting four or five Conditions to handle each possible value, a Switch gives you one clean branch per outcome sitting side by side. Much easier to read, and much easier to add a new case to later without untangling existing logic or apologising to whoever inherits the flow.
A PRACTICAL EXAMPLE
Say you’re processing a support ticket and the next steps depend on its priority. Low, Medium, High, Critical. Nesting that in Conditions would mean checking if it’s Low, if not check if it’s Medium, if not check if it’s High, and so on, basically playing twenty questions with your own flow. A Switch on the Priority field gives you four clean branches instead, each one obvious at a glance.
If you’re only ever checking one thing with two outcomes, Condition is fine. The moment you’re checking one value against three or more possible outcomes, reach for a Switch instead and save yourself the headache.
Got a flow with Conditions nested five deep that really should have been a Switch?
