Does not need to direct current returns the way the touching switch
Thursday, November 20th, 2008 at 11:12 | No commentsCategories: Power SupplyTags: SwitchShort Content: When the user finger bumps into connects the electric circuit public earth an electronic contact, or, because the finger enters time the 60Hz alternating voltage which the neighbor power line radiation in the electrostatic field produces, the ordinary touching switch design can examine the resistance value to drop. But, if the nearby does not have the power line, the equipment from the battery power supply (for example in auto plant), or has not connected the electric circuit public earth time ... -
