According to the relay, when a first contact part and a second contact part are separated from each other or make contact with each other to generate an electric arc, a magnetic field formed by a first permanent magnet can play a traction role on the electric arc, and the arc blowing and arc discharging effects are achieved. The electric arc moves along the contact surface, and when the electric arc moves to the arc isolating groove, the arc isolating groove can play a role in isolating, lengthening and blocking the electric arc, so that the arcing time is shortened. Therefore, the defects that the electric arc ablates the inner cavity and causes relay explosion and the like can be effectively avoided, the product performance can still be ensured even under the condition of high load, and the product failure probability can be reduced. And meanwhile, the first contact part is synchronously contacted with the at least two sheet units, and the first contact part and the second contact part have at least two contact points, so that the shunting effect is achieved, the contact resistance can be reduced, the contact stability and reliability can be improved, and the temperature rise can be reduced.

The application discloses an antenna signal adjusting method applied to a wireless switch panel, wherein the wireless switch panel comprises a wireless communication device and an antenna, and the method comprises the following steps: acquiring a return loss change curve varying with a communication frequency between the wireless communication device and the antenna respectively based on the condition that the wireless switch panel is installed in different medium types; dividing a communication frequency of the wireless communication device into multiple frequency bands, determining a frequency band where a minimum return loss in a communication frequency range is located according to the return loss change curve, and matching the frequency band with a corresponding medium type; detecting a frequency band where a resonant frequency of the current antenna is located in the communication frequency range, and adaptively adjusting based on the matching result. The application further discloses a wireless switch panel and a computer readable storage medium, which can adaptively adjust a network signal.
