Today you will see the seal contact in a way you have never seen before, because we will show you step by step how you will make this well-known SEAL CONTACT, all in a simple and practical way. What is the function of the seal contact? Basic Concepts: The sealing contact is always connected in parallel with the closing contact of the NO pushbutton of a starter. Its purpose is to keep the current flowing or sealing through the contactor coil, even after the operator has removed his finger from the pushbutton. This is due to a basic rule of electrical controls, which is: whenever a coil is energized, all the contacts that belong to it will switch. Those that are open close, and those that are closed open. Therefore, we understand that as soon as the coil is energized, the contact that is in parallel with the pushbutton will close, keeping the coil energized until the other NC pushbutton is pressed. #embaixadordecomandosengehall
