Abstract
A cash box proximity switch arrangement is provided for public telephones and is mounted in an upper portion of a lower housing of the telephone above the vault area. The switch is contained in a sealed housing which prevents contamination from dirt, moisture and the like. A magnet can be arranged so as to provide a bi-stable magnetic circuit between the floor of the lower phone housing and a cash box lid attached to a cash box which has been installed in the vault area of the telephone housing.
