In the electrical industry notation used by PKYS:
-
ON-OFF: Indicates a maintained switch. When you flip it to ON, it stays there until you manually flip it back.
-
(ON)-OFF: The parentheses indicate a momentary action. The switch will stay "ON" only as long as you are physically holding it (like a horn or a starter button).
