Roll Switch

There is an integral roll switch within the Tire Pressure/Sensor Transmitter that must be closed before the transmitter is powered up. This roll switch is open when the vehicle is stopped or below approximately 33 km/h (20 MPH). When the vehicle is moving above 33 km/h (20 MPH) centrifugal force will close the roll switch, powering up the Tire Pressure Sensor/Transmitter unit.

NOTE: The transmitter takes about 2 minutes to fall asleep after the roll switch opens.
