A cam plate is installed around the steering shaft. A pair of switches (A and B) are installed beside it.
When the steering is turned in direction of the arrow, switch A turns on first.
Then switch B turns on.
The cancel unit monitors the on-off sequence of both switches. Once it receives a full set of signals for a right or left
turn, it energizes the solenoid which then moves the turn signal lever back to neutral.
