Mechanical rectifier is a device for converting alternating current to direct current through mechanically controlled switches. The most famous type is the collector , which is an integral part of DC motors , but, before solid-state diodes became available, independent mechanical rectifiers were used for some applications.
Vibrator
This device was the inverse of the vibration transducer . The electromagnet , under the influence of alternating current, caused synchronous vibration of the spring and spring-controlled switching contacts, which converted alternating current to direct current. This device was only applicable for low power applications such as radios .
Motor
These devices acted on the same principle as vibrators, but the switching contacts were controlled by a synchronous motor . These devices were applicable for high-power applications such as electrolysis cells ( electrolyzers ) and electrostatic filters .
