Abstract
A method for detecting a position of a door includes providing a switch having a body with two electrical contacts and a through-channel. Two lever arms extend from the body. Each of the arms is attached to a respective one of the electrical contacts. The arms have a first position relative to each other wherein the contacts are electrically connected to each other, and a second position relative to each other wherein the contacts are electrically disconnected from each other. A hinge pin is inserted through the through-channel of the switch and is also inserted into a door hinge. The arms are biased against a doorjamb and the door, respectively. It is monitored whether the contacts are electrically connected to each other.
