• Suits various circuits in the modelling and hobby market
• Pin terminals for easily soldered joints
• 2A switching capacity
• Designed for operation on a 12V power source
• Double pole double throwWhy use a standard relay?
This relay is perfect for use in home automation, modelling applications or hobbies. It can be mounted onto a PCB board and includes eight easily soldered pins. With its compact size, this relay can be fit into many projects and enclosures. The relay can be run off a 12V 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 connection.
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 with a lower powered switch.
You can use a DPDT relay so that a circuit is connected in one way when there is no power, and another when the relay is activated - for example switching two lights on with a single switch or reversing motion on a DC motor.
