Innovation brings new solutions and makes life more comfortable for us all. An electrical switching device is one of them to appreciate from Automotive engines, industrial machinery to more tangible in household applications, regardless whether it is latching or non-latching Relay. They both represent a different approach to application functionality, bringing your electronics world to life.

Today, we are proudly introducing our own branded RS PRO 3 PDT Relay giving you protection by a transparent polycarbonate cover. Relay rating is showing in ac and dc, and it is crucial never to exceed the maximum switching voltage. Our 3 PDT (Contact Configuration) Relay provides 240 V ac and 30 V dc telling you about the specific amount of power that can be switched through the Relays.

The characteristic click sound indicates the movement of the terminal, which is typical for mechanical Relays. The centre of a Relay is a coil of wire which is powered by AC or DC current. Our non-latching DPDT Relay has a closed position (NC) unless power passes through the circuit, then the Relay opens (NO) part by using an internal coil to generate a magnetic force.

Our range of Non-Latching Relays are reliable, well-respected electronics, offering you competitive price range without compromising quality and you can be sure to find them in stock. If you are looking for more specific information, you can check our datasheet that should answer your burning questions.

Terminal compact size and reliable mechanism of the Relay Circuit has its place in the following applications:

• Automotive engines


• Household applications


• Industrial machinery


• Medical equipment


• Telecommunications equipment

What is the difference between latching and non-latching relays?

Both types of relays in similar in design and function; however, a significant difference between them is that a latching relay will remain in the last position when it was last powered. In contrast, a non-latching goes back to its normal position. This makes each more type of Relay suitable for different applications.

Does it make much difference which way a Relay is installed?

If the coil polarity is backwards, the coil is ultimately shorted by the diode every single time you try to turn it on. Therefore, Relays must always have the correct position (correct polarity); otherwise, it is a matter of time before smoke will appear, meaning Relays are polarity sensitive.
