Yep,
old car radios had them to generate the high tension for the valves !
Another bit of technology from the past when things could generally be fixed, these with a sharp tap at first then resorting to fine emery paper on the contacts.

The device is like a buzzer, only with extra electrical contacts. These contacts connect the 12 V supply to alternately to the ends of a centre taped low voltage primary winding on a transformer. This effectively supplies AC power to the transformers primary winding. The transformer steps the applied 12 V power to a voltage in the range 125 to 300 V which is rectified by a twin diode valve to provide the high voltage needed by the other valves in the car radio.
