I have purchased a wall mounted touch lamp for a bed side reading lamp. The lamp works (turns on, off and 3 levels of brightness) when it is held against the wall, held in the hand, anywhere EXCEPT when it is mounted on the wall mounting plate that came with it. When the lamp is mounted on the wall mounting plate it does not work any any shape or fashion. I can hold the lamp (wearing gloves) and touch the lamp to the mounting plate and then it works. Any ideas as to how to get this lamp to work and be properly mounted at the same time?
