Patent ID: 7277265

Claim:
An electronic control switch for a vehicle powertrain application, said control switch comprising: a control module for enabling/disabling a vehicle driveline application, said control module comprising: a first input connected to one of a first reference voltage and a second reference voltage; a second input connected to one of the first reference voltage and the second reference voltage; a first failure state based on said first input and said second input both receiving the first reference voltage; a default off state based on said first input receiving the second reference voltage and said second input receiving the first reference voltage; an enable state based on said first input receiving the first reference voltage and said second input receiving the second reference voltage; and a second failure state based on said first input and said second input both receiving the second reference voltage; and an inverse reference voltage operator connected to both said first input and said second input, said inverse reference voltage operator connecting said second input to the second reference voltage when said first input is connected to the first reference voltage and connecting said second input to the first reference voltage when said first input is connected to the second reference voltage.
