Abstract
An electrical device for signaling a change in physical conditions within a vehicle pneumatic tire mounted on a rim has a sensing element containing at least two electrical contacts which are closed or open to the flow of an electrical current depending upon the physical conditions in the tire, a pair of electrodes connected to the contacts and passing through the wall of the rim, an electrical signaling circuit disposed outside the rim, connected with the electrodes and controlled by the position of the two contacts, the electrical circuit being enclosed in a mass of cross-linked synthetic resin to protect it from excessive wear due to dust, rain and mud.
