1. A key-operated electrical switch including in combination, a switch housing enclosing a switch mechanism therein, first moveable means coupled to said switch housing for operating said switch mechanism, rocker means coupled to said switch housing and moveable by the switch operator relative to said first means, and a key member for selectively connecting said first means and said rocker means, said key member extending through said rocker means and into said first means thereby connecting said first means and said rocker means so movement of said rocker means moves said first means and said key member in unison therewith to operate the switch, with said key member being removed from said first means and said rocker means said rocker means moves relative to said first means thereby rendering the switch inoperable

3. A key-operated electrical switch including in combination, a switch housing enclosing contact means and a bridge member, a carrier member for operating said bridge member for selectively opening and closing said contact means, first and second support means connected to said switch housing in a spaced relation to one another, a pin member extending between said support means, said carrier member being rotatingly mounted to said pin member between said support means, said carrier member moveable between a first or ''''on'''' position and a second or ''''off'''' position for operating said contact means, a rocker member having a body with a hollow portion therein and a leg member integral with said body and extending outwardly of the hollow portion, said leg member extending into said carrier member and being rotatingly mounted to said pin member, said carrier member and said rocker member being moveable relative to one another about said pin member with the hollow portion of said rocker member rotating about said carrier member, and key means removably positioned to extend through said rocker member and into said carrier member, said key means in said position connecting said rocker member to said carrier member so the same move in unison with said key means and not relative to one another to selectively open and close said contact means, and said key means being removed from said position, said rocker member moves relative to said carrier member rendering the switch inoperative.
