Steering Pad Switch Circuit

Steering Pad Switch Circuit

DESCRIPTION

This circuit sends an operation signal from the steering pad switch to the navigation receiver assembly. If there is an open in the circuit, the navigation system cannot be operated using the steering pad switch. If there is a short in the circuit, the resulting condition is the same as if the switch were continuously depressed. Therefore, the navigation receiver assembly cannot be operated using the steering pad switch, and the navigation receiver assembly itself cannot function.
