A cooling plate, the hybrid electronic circuit and a circuit board connection plate, are mounted flat at the bottom of a cup-shaped vessel with a reentrant tube for an iron core leg, in which vessel the secondary winding on its spool and a primary winding set inside the spool are put for being imbedded in a casting resin. The vessel and its contents fits over the central core leg of an E-shaped stationary armature of a magneto generator for a one-cylinder internal combustion engine.

The laminations of a stack that form an iron core for a magneto armature are provided with wart-like deformations produced by through-stamping, so that pressing the stack together will provide a press-fit at the locations of the deformations. The core is mounted by screws through mounting holes respectively in the yoke and at the end of one leg of an E-shaped core, while the press-fits produced by superposed deformations hold the rest of the core together against warping and twisting. Protuberances from the annular cup casing, which contains the winding mounted on the middle leg of the core, grasp the lamination stack in a region remote from the mounting holes to prevent the press-fit locking of the laminations from loosening.

An insulating cup-shaped body (29) that is screwed into the rim (11) of a vehicle wheel prevents conduction of heat (generated by the brakes, for example) from heating the metallic body (16) that forms a reference pressure chamber closed off by a membrane (17) from the inflated interior of a vehicle tire. The membrane (17) is set slightly within the rim of the cup for protection during tire changes. The chamber and switch housing (16) and a spool (27) for the coil of a resonant circuit form a preassembled unit that is snapped into the insulating cup and cemented into place. The relatively large coil diameter adds to the economy of the device, permitting the use of a small capacitor. The temperature of the gas sealed in the reference pressure chamber (18) by closure of the filling bore with a steel ball (25) follows the temperature of the interior of the tire and reliably opens the resonant circuit if the tire pressure falls below a prescribed limit. The condition of the resonant circuit is sensed by a fixed miniature oscillator mounted on the axle.
