1. A key structure with illumination function, comprising:
- a key plate having a front end with which a key head is engaged for extending into a key hole, a middle section of the key head being disposed with a locating diaphragm;
a cell;
a light emitting means disposed on the locating diaphragm of the key head, two terminals of the light emitting means being respectively extended to two electrodes of the cell, one of the terminals being spaced from the cell in normal state and able to contact with the cell when depressed; and
a grip housing composed of a first and a second casing for enclosing the above elements, one side of the grip housing being disposed with a movable depression button adjacent to one side of the cell, whereby by means of depressing the depression button, the spaced terminal of the light emitting means is pushed to contact with the electrode of the cell to form a closed circuit, enabling the light emitting means to provide illuminating effect.

Abstract
A key structure with illumination function including a grip housing composed of a first and a second casing, a key plate enclosed in the grip housing and having a key head extending out of the grip housing, a cell disposed beside the key plate and a light emitting diode having two terminals extending to two electrodes of the cell. By depressing a depression button, the terminals of the light emitting diode are electrically connected with the cell to form a closed circuit so that the light emitting diode can emit a light beam to illuminate the circumference of the key hole. Accordingly, in a dim place, a user can easily use the key to unlock the lock.
