Normally closed (NC) and normally open (NO) contacts are terms used in the context of electrical switches and relays, but what’s the difference between a normally closed vs normally open switch? These terms describe the default state of a contact in a switch or relay when no external ...
We can tell this switch is a normally-open (NO) switch because it is drawn in an open position. The lamp will energize only if someone presses theswitch, holding its normally-open contacts in the “closed” position. Normally-open switch contacts are sometimes referred to in the electrical ...
