start signal
Race initiation prompt
A start signal is a cue that initiates an action or event—the gunshot beginning a race, the green light launching cars, the whistle starting a match.
In technical contexts, it's an electronic or mechanical trigger that activates a system or process: The timer begins counting when it receives the start signal.
