Electro-mechanical latch relay with mechanical locking for extended period of stable operation

摘要

A mechanical latch relay started by a current pulse is disclosed which comprises an electromagnetic generating unit, a connecting means and a mechanical locking means, and which can maintain the existing operation state when the current pulse starting the relay disappears, and it changes its operation state when another current pulse is provided, and then it keeps the operation state even if the pulse disappears so that it can provide a stable operation state of current on/off unnecessary to be provided with a current for a long time, which is stated to provide an effective control for current on/off.
