   Eight switches offer 256 (2 8) combinations, which is equivalent to one byte. A tri-state type DIP switch can be in one of three positions (+, 0, −) which allows more codes than a binary DIP switch. For example, 8 pole tri-state DIP switches offer 6,561 (3 8) combinations/codes compared to 8 pole binary switches' 256 (2 8) combinations/codes ...

9. Starter solenoid - Wikipedia

   en.wikipedia.org/wiki/Starter_solenoid

   The starter solenoid is sometimes called the starter relay, but many cars reserve that name for a separate relay which supplies power to the starter solenoid. In these cases, the ignition switch energizes the starter relay, which energizes the starter solenoid, which energizes the starter motor. The starter solenoid is above the starter motor.
