Inquiry (采购产品): switch needed We need to have a switch that is open when it receives a 5 volt signal and is closed when it is not. When I mean open - it needs to pass 9 volts or more. **** Hidden Message ***** Neal Gliksman PA 19335 USA Company: Molecular Devices Corporation E-mail: neal.gliksman@moldev.com **** Hidden Message ***** neal.gliksman@moldev.com
