Why does hitting the remote a couple times make the batteries work again?
In: Engineering
The lower the voltage in any given system, the more it is prone to failure from any little extra resistance from a marginal connection. Most remotes use (2) AA batteries, giving you around 3 volts to work with. That is very low voltage, which makes that kind of system very prone to problems if a contact or connector or battery is a bit oxidized or loose.
Percussive maintenance can often scratch through a bit of the oxide, or improve a weak spring/mechanical connection.
