FLASHLIGHT AND SWITCH ASSEMBLY
First Claim
1. A switch cover assembly for use with a magnetic reed switch operatively mounted in the external wall of a device comprising:
- a. switch cover formed with a chamber and having a front end, back end, two side walls, an open bottom and a top face formed with an opening;
b. a switch button slidably mounted over the opening in the top face of the switch cover;
c. a magnet having its north and south poles in alignment with the front and back ends of the switch cover and having its north and south poles positioned parallel to the longitudinal dimensions of the contact arms of the reed switch, affixed to the underside of the switch button for movement therewith within the chamber;
d. two strips of magnetizable steel, one strip of steel being mounted at each end of the switch cover, parallel to the upper face of the switch cover, the inner end of each steel strip bent perpendicular to the strip, the perpendicular faces of the strips being substantially parallel to the ends of the magnet, the perpendicular faces of the strips being a predetermined distance from each other with respect to the magnet, so that when the magnet is magnetically held at one steel face it will be directly over the center portion of the reed switch and when the magnet is magnetically held by the second steel strip it will be held away from the center portion of the reed switch; and
e. means to mount the switch assembly on the external wall of a device.

Abstract
An improved flashlight construction which substantially reduces the possibility of arcing, having a glass enclosed magnetic reed switch electrically connected to the conductor strips along the wall of the flashlight case and having the magnet required to close the contact arms of the reed switch incorporated into a slidably mounted switch cover, the conductor strips being electrically connected in a fixed position between the conductor rings at the ends of the case. In a modified form of the switch assembly, the magnet is positioned in a preformed case which is mounted on the outside of the flashlight case so that the movable parts of the switch are completely separated from the internal parts of the flashlight. Other modifications of switch covers having magnets mounted therein which can be locked in either the '"'"''"'"''"'"''"'"'On'"'"''"'"''"'"''"'"' or '"'"''"'"''"'"''"'"'Off'"'"''"'"''"'"''"'"' position by means of magnetizable steel are also shown.
