A device that automatically starts an engine or system without manual activation, or something that triggers itself into operation.
From auto- (self) + starter (device that begins something). Common term from automotive technology, particularly early electric starters that replaced hand-cranking.
Before autostarters, you had to crank car engines by hand like starting a lawnmower—dangerous because the engine could kick back and break your arm. The electric autostarter made cars way safer and easier.
