Take control of higher powered circuits
Use this change over relay to change between two independent circuits with ease. Great of projects or models, this relay would let you change between two completely different circuits such as a red and green light that both run off different voltages. With four spade connectors to connect to your project and two for power this relay is easy to your circuit. Designed to run off 240V this relay can handle a maximum switching power up to 9,000VA with an operating time of 20ms and a release time of 25ms.

Switch between two circuits
With this change over relay there are two terminals to connect your normally closed circuit and two separate terminals for your normally open circuit. When the relay has power, the two normally open terminals are connected – which makes this the active circuit. If the power is removed the normally open circuit breaks as the connection moves to the two normally closed terminals, activating this circuit. Unlike single pole double throw relays, this relay can switch between two completely different circuits without using a single common pin.
