切换

When the coil of the relay is at rest, the common terminal (30) and the normally closed terminal (87a) have continuity.

虽然继电器很少为逻辑控制使用，但它们在需要大量功率负载切换开关时仍然是必不可少的。

If the switched current is too high, the resulting temperature increase and contact arcing will degrade the relay and shorten the contact life.

如果切换电流太高，造成的温度升高和接触电弧将会劣化继电器并缩短接触寿命。

This film can increase the relay contact resistance, which can make the switched voltages erratic when measuring or sourcing low voltage.

这层氧化膜会增大继电器接触电阻，从而造成测量或提供低电压时被切换电压的不规律性。

The invention discloses a fast switching method of a relay station and a device thereof, and a wireless communication network.

本发明公开了一种中继站快速切换方法、装置及无线通信网络。
