Device with Three Detectable Switches

      Disclosed is a device with three detectable switches which can
recognize different types of batteries.  Based on information from
this device, a power management microcomputer on the system can
manage to consume the energy of a battery in the best efficiency.

      There are three major battery types in the field.  They
are similar in shape other than the way they are recessed on the
surface.  This device senses the difference of recess size and
location using three detectable switches.

      The Figure shows how to detect them.  When #1 battery is
inserted into this device, SW1, SW2, and SW3 are pushed and become
on.  When #2 is inserted into it, SW1 and SW3 are pushed and become
on.  When #3 is inserted into it, SW1 is pushed and becomes on.  And
the power management microcomputer manages the battery consumption
based on the switch information.

      The system is able to recognize more battery types than the
current ones if additional switches are applied to this device and/or
the system.
