Abstract
A modular telephone keyset instrument is arranged within a rectangular casing having indentations in the top for receiving a telephone handset. Electrical (electronic) circuits are provided on a mother PC board, a daughter PC board and a key switch PC board, stacked within the housing from bottom to top, respectively. The daughter and keyset PC boards are connected to the mother PC board by ribbon cables. A hook switch, mounted on and attached to the daughter PC board extends through one of the indentations in the top to sense whether the telephone handset is placed in the indentations.
