Mercury is better, the conductivity of the mercury switch contact resistance between the electrodes is less than 100 m Ω commonly. (4) mercury switch allows current depends on the electrode materials, tungsten electrode for the maximum allowable current 10. A, the general wire normally maximum allowable current 1 a. (5) due to gravity to determine mercury switch on and off by mercury, so it can work reliably for a long time.

TXD: sender, usually expressed as the sender, normal communication RXD must answer another equipment. RXD: receiving end, usually expressed as the receiver, the normal communication TXD must answer another equipment. When normal communication itself TXD pick up equipment RXD forever! Since collect spontaneous: normal communication TXD RXD connect other devices, so if you want to receive their send data as the name implies, is receiving themselves to send data, is directly connected to the RXD TXD itself, that is, used to test whether the sending and receiving of normal itself, is the most simple test method is the fastest, when problems arise first do this test to determine whether the product failure. Also known as the loopback test.
