Abstract
Sensors and methods for detecting attachment to a surface are disclosed. The sensors include a housing having an inner surface, an outer surface and a passage extending through the housing. An elongated member or fastener extends though the passage and protrudes from the outer surface of the housing to attach the sensor to a surface. First and second electrical contacts are disposed within the housing so that when the sensor is attached to the surface an electrical path is formed between the first and second electrical contacts.
