A flip cover and hinge operate as a rotary switch to select the mode of operation of a communications device. Multiple contacts are located on the sides of the inner surface of the flip cover and a single contact is located on each side of the body of the communications device. Each contact located on the sides of the inner surface of the flip cover represents a different mode of operation for the communications device. As the flip cover rotates from a closure position to its final position as a stand, the mode of operation of the communications device changes as the contact from the body of the communications device connects with one of the contacts on the flip cover. Three modes of operation are presently implemented: the KEYPAD mode, the SMARTPHONE mode, and the SPEAKERPHONE mode.

1. A system for engaging different modes of operation of a device, comprising:a first portion having a plurality of sets of electrical contacts and a plurality of resistive circuits coupled between said sets of electrical contacts, each set of electrical contacts representing a different mode of operation; a second portion, coupled to said first portion, having a set of electrical contacts, wherein different sets of contacts are made or broken based on the relative position of said first portion to said second portion; and a processor for determining which of said plurality of sets of electrical contacts from said first portion are electrically connected to said set of electrical contacts from said second portion by determining whether said electrical connection is based on a voltage measurement from one of said plurality of resistive circuits in said first portion or a voltage measurement from said second portion, and enabling said system to operate in one of a plurality of operating modes based on said measurement.
