Abstract (en)
[origin: WO2005024879A1] Switchgears wherein piezoelectric converters have the function of an actuator are known. According to the invention, a magnetic actuator (5) is associated with the piezoelectric converter (11) as an actuator for unlocking the switch latch (10), in order to provide an overload and short-circuit protection. The piezoelectric converter (11) can be used in conjunction with the solenoid as a sensor for determining the circulating flow.
