a toggle control button of a toggle controller is exposed when one or more sliders are in the second position; and
the toggle controller is configured to:
toggle the first activation button to produce either the first therapy signal, a third therapy signal, or both; or
toggle the second activation button to produce either the second therapy signal or a fourth therapy signal, or both.

3. The electrosurgical device of claim 2 , wherein the first therapy signal is bipolar coagulation.

4. The electrosurgical device of claim 2 , wherein the second therapy signal is bipolar cut and the fourth therapy signal is monopolar cut.

5. The electrosurgical device of claim 2 , wherein the second therapy signal or the fourth therapy signal is monopolar cut or bipolar cut.

6. The electrosurgical device of claim 2 , wherein the one or more sliders disable the toggle controller when the one or more sliders are in the first position.

7. The electrosurgical device of claim 1 , wherein the electrosurgical device includes a third configuration where the blade is extended beyond the distal end of the first working arm and the second working arm.

8. The electrosurgical device of claim 7 , wherein a toggle control button of a toggle controller is exposed when the electrosurgical device is in the third configuration so that the toggle controller is configured to:
toggle the first activation button to produce either the first therapy signal, a third therapy signal, or both; or
toggle the second activation button to produce either the second therapy signal or a fourth therapy signal, or both.

9. The electrosurgical device of claim 1 , wherein the one or more sliders are a first slider and a second slider.

10. The electrosurgical device of claim 9 , wherein the first slider covers the first activation button, the second activation button, or both in one or more positions.

11. The electrosurgical device of claim 9 , wherein the second slider is prevented from moving when the first slider is in the first position and permitted to move when the first slider is in the second position.

12. The electrosurgical device of claim 9 , wherein the first slider, the second slider, or both are movable from the first position, to the second position, and a third position.

13. The electrosurgical device of claim 12 , wherein the first slider when in the third position extends the distal end of the blade beyond the distal end of the first working arm and the distal end of the second working arm.

14. The electrosurgical device of claim 9 , wherein a blade is movable with the first slider or the second slider.

15. The electrosurgical device of claim 9 , wherein the first slider when in the first position positions the distal end of the blade within the distal end of the first working arm and the distal end of the second working arm.

16. The electrosurgical device of claim 9 , wherein the first slider when in the second position aligns the distal end of the blade with the distal end of the first working arm and the distal end of the second working arm so that the distal end of the blade and the distal end of the first working arm and the distal end of the second working arm are flush.

17. An electrosurgical device comprising:
forceps including:
(i) a first working arm,
(ii) a second working arm,
(iii) a first activation button,
