No Power To Relay Switch at Amelia Bryant blog

No Power To Relay Switch. Normally closed relays allow power to flow through their contacts when in the default position (no power). Let the transistor be powered through a base resistor connected to. When power is introduced to the coil of the relay the switches will. Relays are rated based on their capacity to. Relay contacts are designated as either normally open (no) or normally closed (nc), depending on their state when no power is applied to the relay. When there is no power applied to the relay coil, the common (c, or com) is connected to nc. In summary, relays are typically specified as either no or nc when no power is applied. When the power is switched off, a spring pulls the contact back up to its original position, switching the second circuit off again. Use an npn transistor to power the relay.
