Abstract
A multi-part closure provides remote indication of a secured or unsecured state of the closure. The closure includes first and second mating members that when engaged define a secured state and when disengaged define an unsecured state. A self-contained transmitter is disposed in the first member. A switch is disposed in the first member in electrical communication with the transmitter. The switch is positioned within the first member for engagement by the second member when the first and second members are mated with and secured to one another. A remote receiver provides indication of the engage or disengaged state of the first and second members.
