5V DC 2A DPDT Relay
• Suitable for various circuits in the modelling and hobby markets
• Pin terminals for easily soldered joints
• 2A switching capacity
• Designed for operation on a 5V DC power source
• Double pole double throwWhy use a standard relay?
This relay is perfect for use in home automation, modelling applications or hobbies. The relay can be mounted onto a PCB board, and comes with eight easily soldered pins. Its compact size means the relay can fit into a wide range of projects and enclosures. The relay can be run off a 5V power supply.
What does double pole double throw (DPDT) mean?
A single pole has one common terminal that can be switched between an NO (normally open) terminal and an NC (normally closed) terminal. The double pole has two poles connected this way, so there are two NO contacts and two NC contacts. When the relay’s coil is not powered, the common connector will be linked to the NC connections. When the relay is powered, the common connector will be linked to the NO connections.
Why would I use a relay?
There are several advantages to using a relay. You may want to switch a high current to a lower current, for example controlling a mains operated device using a lower powered switch.
You can use a DPDT relay to connect a circuit in one way when there is no power, and another when the relay is active - for example switching two lights on with a single switch or reversing the motion on a DC motor.
