Hello john;

A stop start retain relay control circuit is a latch circuit which utilizes momentary switches, (usually push button switches) which will either START or STOP a motor or process or any other load.

The output RELAY will RETAIN the state of being ON or OFF depending on which button was last pushed.

Such circuits may have many variants, including LIMIT switches, INTERLOCKS, and be implemented in AC or DC circuits, and also utilizing solid state logic devices.
