Abstract: A handle is disclosed for use in conjunction with a key telephone printed wiring board. The handle is constructed having windows along the front surface and electrical contacts grouped behind each window. A multicontact connector is optionally connected to various of the contacts within each group and the group of contacts to which the connector is attached at any given time is easily ascertained by viewing through the associated window. The window, in addition to providing a means for determining the selected options without resorting to the removal of the board from the network, also serves to protect the individual connectors from inadvertent removal.
