A five-switch keypad apparatus having four diodes that multiplex the switch contacts onto three sense terminals. The three sense terminals create a binary code that defines eight possible switch states. The eight states are used to indicate each individual switch closure, a lack of a switch closure, and two simultaneous dual switch closures. In an application, a decoder, connected to the three sense terminals, converts the sequence of binary codes into three control signals. The three control signals can control a door lock, a trunk lock and an automatic lock function.
