1. A wire guide apparatus for a staple gun having a staple driver at a front end thereof, the apparatus comprising: a housing positioned on the front end of the staple gun forward of the staple driver;the housing holding a cam switch, a cam shaft and a cam, the cam switch being movable to rotate the cam; anda substantially planar wire guide having a first cutout adapted to be positioned over a wire or cable and a second cutout adapted to receive the cam;wherein the cam is movable within the second cutout to move the wire guide linearly from a first position, in which the first cutout is not extended from the staple gun, to a second position in which the first cutout is extended from the staple gun;wherein at least a portion of the cam switch has an arcuately shaped portion received in a correspondingly shaped arcuate recess in the housing;wherein the cam switch is rotatable between a first position, in which a bearing surface of the cam is urged against an upper surface of the second cutout in the wire guide, and a second position, in which the bearing surface of the cam is urged against a lower surface of the second cutout in the wire guide;wherein said first and second positions of the cam switch and cam correspond to the first and second positions of the wire guide;wherein, in the first position and the second position, the longitudinal axis of the cam is at an angle with respect to a longitudinal axis of the wire guide to lock the wire guide in the first position and the second position; andwherein, in the first position and the second position, the longitudinal axis of the cam cooperates with the wire guide to lock the guide in the first position and the second position without an additional locking mechanism. 2. The wire guide apparatus of claim 1, wherein the staple gun is provided with a substantially planar safety element having an aperture through which the cam shaft passes, the aperture being elongated so that the safety element can slide in the housing without affecting the wire guide. 3. The wire guide apparatus of claim 1, further comprising a light emitting diode positioned forward of the wire guide. 4. The wire guide apparatus of claim 1, wherein the housing has an open back, a forward slot to receive the wire guide, a rear slot to receive a planar safety element, and a central channel on the front of the housing to receive the cam switch, a light emitting diode (LED) and an LED subhousing in a low profile manner. 5. The wire guide apparatus of claim 1 wherein the cam switch comprises a rotary switch. 6. The wire guide apparatus of claim 1 wherein the second cutout has a closed surface on one side of the cam to prevent rotation of the cam past the closed surface. 7. The wire guide apparatus of claim 6 wherein the closed surface of the second cutout limits rotation of the cam to less than a full rotation. 8. The wire guide apparatus of claim 6 wherein the closed surface of the second cutout permits rotation of the cam greater than 180 degrees. 9. The wire guide apparatus of claim 6 wherein the second cutout has an open end spaced apart from the closed surface; and wherein the second cutout is provided with rounded corners so that the second cutout is wider adjacent the closed surface than at the open end for receipt of a bearing surface of the cam in the rounded corners. 10. The wire guide of claim 9 wherein the cam switch is rotatable between the first position for retraction of the wire guide, and the second position for extension of the wire guide; and wherein the cam is rotated past center in the second position such that if a force is applied upon the wire guide in a direction from extension to retraction, the wire guide translates, thereby rotating the cam bearing surface toward the closed surface of the second cutout, and thereby preventing rotation of the cam away from the closed surface, and consequently preventing retraction of the wire guide. 11. The wire guide of claim 10 wherein the cam locks the wire guide in the extended position when the cam is rotated to the second position. 12. The wire guide of claim 9 wherein the cam switch is rotatable between the first position for retraction of the wire guide, and the second position for extension of the wire guide; and wherein the cam is rotated in the second position inclined toward the closed surface such that if a force is applied upon the wire guide in a direction from extension to retraction, the wire guide translates, thereby rotating the cam bearing surface toward the closed surface of the second cutout, and thereby preventing rotation of the cam away from the closed surface, and consequently preventing retraction of the wire guide. 13. The wire guide of claim 12 wherein the cam locks the wire guide in the extended position when the cam is rotated to the second position. 14. A staple gun comprising: a housing;a staple driver oriented at an end of the housing;a rotary switch mounted for rotation on the housing;a cam mounted for rotation on the housing, the cam being connected to the rotary switch so that rotation of the rotary switch rotates the cam; anda wire guide mounted to the housing for translation relative to the housing, the wire guide having a first cutout adapted to be positioned over a wire or cable and a second cutout sized to receive the cam;wherein the rotary switch is rotatable between a first position whereby a bearing surface of the cam is urged against an upper surface of the second cutout in the wire guide for retraction of the wire guide, and a second position whereby the bearing surface of the cam is urged against a lower surface of the second cutout in the wire guide for extension of the wire guide; andwherein the cam is rotated past center in the second position such that if a force is applied upon the wire guide in a direction from extension to retraction, the wire guide translates, thereby rotating the cam bearing surface toward a closed surface of the second cutout, and thereby preventing rotation of the cam away from the closed surface, and consequently preventing retraction of the wire guide. 15. The staple gun of claim 14 further comprising a substantially planar safety element having an aperture through which the cam shaft passes, the aperture being elongated so that the safety element can slide in the housing without affecting the wire guide. 16. The staple gun of claim 14 further comprising a light emitting diode (LED) positioned forward of the wire guide. 17. The wire guide of claim 14 wherein the cam locks the wire guide without an additional locking mechanism. 18. A staple gun comprising: a housing;a staple driver oriented at an end of the housing;a rotary switch mounted for rotation on the housing;a cam mounted for rotation on the housing, the cam being connected to the rotary switch so that rotation of the rotary switch rotates the cam; anda wire guide mounted to the housing for translation relative to the housing, the wire guide having a first cutout adapted to be positioned over a wire or cable and a second cutout sized to receive the cam;wherein the rotary switch is rotatable between a first position whereby a bearing surface of the cam is urged against an upper surface of the second cutout in the wire guide for retraction of the wire guide, and a second position whereby the bearing surface of the cam is urged against a lower surface of the second cutout in the wire guide for extension of the wire guide; andwherein the cam is rotated in the second position inclined toward the closed surface such that if a force is applied upon the wire guide in a direction from extension to retraction, the wire guide translates, thereby rotating the cam bearing surface toward a closed surface of the second cutout, and thereby preventing rotation of the cam away from the closed surface, and consequently preventing retraction of the wire guide. 19. The staple gun of claim 18 further comprising a substantially planar safety element having an aperture through which the cam shaft passes, the aperture being elongated so that the safety element can slide in the housing without affecting the wire guide. 20. The wire guide of claim 18 wherein the cam locks the wire guide without an additional locking mechanism.
