Why do bikes have a solenoid?

No Stupid Questions@lemmy.world · 1 day ago

I understand that it is a switch to connect the battery to the sarter. But why not just make the ignition switch the actual switch?

Is it because the amps are high so the switch would be too big to comfortably use? Because if that is the case, wouldn’t a simple mechanical solution be better?

The other comments are correct. Also, a solenoid that switches another set of contacts is called a relay, or contactor.
