JIANGXI WEIQI Products
A relay works as a switch that is electrically operated to allow the internal operation of a switching mechanism. It is characterized by having open and close circuits that control its contact with another circuit piece. There are two possible scenarios when a relay is working but is not energized, NO or normally open and NC or normally closed. Both applications promote the relay’s change of work state and convert small continuous electrical stimuli into larger currents.
As a professional manufacturer of this, WQE offers all sorts of its kind. There are three main varieties available and are detailed as follows:
Electromechanical – A switch that is used by electrical machines to control high-power electrical devices.
Automotive – This is a common type of electromechanical relay present in all vehicles such as cars, trucks, and vans.
Latching – A two-position electrically-actuated switch to ‘set’ and ‘reset’ the relay. The latching relay is preferred when there is a need to control large currents with smaller ones.

WQE manages to produce multiple relays for different industries; it has dedicated sections and series that will help present all of its products to the market. The main product categories distributed are Communication Reed Relays, Power Relays, Automotive Relays, Magnetic Latching Relays, Manganin Diverter, and Current Transformer.

How To Test A Relay?
Testing a relay is a simple process, and since there are many types of relays, we will show you our general ideas of how you can execute the process of testing a relay.
So, let’s get started!
1) Measuring contact resistance
You can apply the specified working voltage to the relay coil; by using a multi-meter, you can detect the on-off condition of the contact at the “R×1k” gear. If the power is not applied, the normally open contact does not work, and the normally closed contact conducts. On the other hand, when the power is turned on, you should hear the pick-up sound of the relay.
2) Measuring coil resistance
The resistance value of the relay coil can be measured with the multi-meter at R×10Ω gear to determine whether the coil is open.
3) Measuring of pull-in voltage and current
You can use an adjustable regulated power supply to input a voltage set to the relay and connect an ammeter in the power supply circuit to monitor. Then, slowly increase the power supply voltage, and when you hear the pull-in sound of the relay, write down the voltage and current. By trying several times, you can get the average value.
