Use of DB socket tips DB socket selection "30V / 0.5 a" for example, this socket allows the current is 0.5 a, insulation voltage class is 30V. Here "0.5 a" is the most important, it is the maximum safe current conductor design. Anything over 0.5 A, it'll heat up, oxidize, malfunction. And 30V is the index of insulating material, there is a difference between the two. DB socket how to weld the position of oxide to scrape, to apply less solder paste, preferably with a 100W soldering iron fast welding, and then blow with the mouth, so that it did not wait for Melting Gel cooling. DB socket positive and negative socket, there will be marked some also marked voltage: DB socket eliminate spark if it is DC very easy, you can add a transistor switch circuit behind the socket of the board, turn the power on with a small key switch, there is no current when plugging in the power supply, of course there will be no spark, generally using PNP transistor is the simplest, but to choose a high current transistor or MOS, there is a choice of relay, through the button switch relay to switch power supply, but relay to choose a good, AC then to use the SCR.
