While we are a security and alarm monitoring company, we also tend to get some requests for products from people that aren't looking for security. Recently we were contacted by Philip J. Beards who designs beautiful custom pool tables and other cabinetry and furniture in London. He had a project he was working on that required some contact switches that would operate lighting within a wine cabinet he was designing. The idea behind the design was that when the cabinet is opened, the lights would turn on to illuminate the inside of the cabinet. He was planning to install the contact switch in the frame of the cabinetry and the magnet in the sliding door.
Philip's problem was that he could not find the contact switches from local London alarm companies or from anyone in mainland Europe. He had ordered some contacts from American companies, but with all of the switches he had tried, the circuit was only completing when the door was closed. Therefore, his lights were turning on when the sliding door was shut and no one could see his awesome work. He contacted us because he saw that we carried many types of contact switches.
After discussing how the alarm industry views normally open and normally closed switches, we decided the Honeywell 944-2GY switches would be the best option since they allow for normally open and normally closed configuration. In the alarm industry, we consider normally closed to be a switch that completes the circuit when the magnet is close to the contact because the door closed is the "normal" position. However, an electrician would consider that same contract to be normally open. The beauty of the 944-2GY contact is that it has three wire leads, a common, a normally closed and a normally open, so that Philip was confident he could configure the switch to do exactly what he needed.
These pictures don't do the final product justice, but you can see that the interior lights are on when the sliding door is open. You can also see one of Philip's gorgeous custom pool tables he built for the same customer.
