Tips: What are the contacts of relay?

Relay is a switch used for circuit control according to the electrical input signal. And the current in the control circuit relies on the “normal open” and “normal close” of the relay contacts. The contact of relay in a disconnected state when the coil is uncharged, the contact is called normally open contact. And the contact of relay in a closed state when the coil is uncharged, the contact is known as normally close contact. In the same relay, there may be a group or a number of groups of normally open or normally closed contacts.

The contact resistance has the greatest influence on the reliable operation of the contact. Because the existence of contact resistance, when the current passes through the closed contact, the relay contact resistance will consume a certain amount of power, this will increase the contact temperature, making contact material soften and deform. The factors that affect the contact resistance of relay contact include the size of contact pressure, the choice and use of contact materials, the form of contact structure and the use environment of contact, etc. For users, it’s not only to choose the right model, but also to ensure that the use environment of the relay to meet the requirements. It is better to make the relay avoid the erosion of water vapor, dust and harmful gas. Measures should be taken to reduce the contamination of contacts, so as to ensure the stability and reliability of the contacts.
