Inquiry (采购产品): Switch Do you know of some type of switch that can be put in a door so with the door closed it is off and when the door is open it is on. This switch will work something else that will work a light or bell for warning you that someone has opened the door. Everything could be 110 or DC to 110 power I don't care. I just want to be told when someone opens the door. **** Hidden Message ***** James Lynch 45 Meadoe Street Georgetown, SC 29440 USA Company: Enterprise Farms Phone: 843-546-7077 E-mail: jmljmlrv@earthlink.net **** Hidden Message ***** jmljmlrv@earthlink.net
