NC/NO Change Over Relays - 40/50 Amp

Understanding NC/NO Change Over Relays and Their Applications

A Change-Over relay is the most common type of relay. These have 5 pins and a body with two contacts connected to a common terminal. The Change-Over relay can control two different circuits, one NO and one NC. As the name suggests, it can also switch between these two types depending on your specific needs. No matter what type of circuit (NO, NC, or both), a change-over relay can switch current from one component to another. Picker offers several different Change-Over relays, with or without brackets. The flux tight relay combats dust and moisture. A relay with a built-in resistor offers internal resistance, which protects your application from high voltage spikes and keeps your connection secure. Picker also offers weatherproof relays for battling the elements. For more information regarding relays, check out the Del City Blog here.
