A relay of the present disclosure includes an insulation cover (21), a first yoke plate (22), a contact assembly (3), a driving assembly (4) and a pressure relief valve assembly (5). The first yoke plate (22) connects with the insulation cover (21) and encloses a contact chamber (27) with the insulation cover (21). The first yoke plate (22) is provided with a pressure relief hole (221). The driving assembly (4) connects with the movable contact piece (32) and drives the movable contact piece (32) move. The pressure relief valve assembly (5) is on the first yoke plate (22) and configured to close the pressure relief hole (221) when a gas pressure in the contact chamber (27) is less than a threshold and configured to be broken to open the pressure relief hole (221) when the gas pressure in the contact chamber (27) is greater than or equal to the threshold.
