#Safety_Relay or #kill_switch for #Electrical_safety during machine operation.
Even if a machine's emergency stop is pressed, contact welding at its normally closed contact points will allow the machine to run continuously.
This will create a dangerous situation, endangering the life of the operator, and can also cause severe damage to the machinery.
Safety relays can effectively isolate quite dangerous machines, when a working contactor or relay is faulty.
The operation and installation of the safety relay are explained here in a descriptive way for easy understanding.
