<p>The present invention relates to a three-position operation device. In the present invention, a housing (10) which is made of a conductive material is placed. A fixing connection unit which is fixated and connected to one side circuit is placed in the housing (10). First and second operating connection units (16, 18) are placed on the other side. A driving cam (20) is installed in an internal space (12) of the housing. First and second connection channels (24, 24′) are formed on both surfaces of the driving cam (20). A first operating electrode (30) and a second operating electrode (40) are installed in the first and second operating connection units (16, 18) to be inputted and outputted inside and outside the housing (10). The first operating electrode (30) is connected to the driving cam (20) by a first line tool (32) and the second operating electrode (40) is connected to the driving cam (20) by a second line tool (42). A first interlocking pin (36) and a second interlocking pin (46) are operated while being placed on the first connection channel (24) and the second connection channel (24′) to be connected with the driving cam (20) in the first line tool (32) and the second line tool (42). According to the present invention as above, the composition is formed relatively and simply and the durability and performance can be improved because the first and second interlocking pins (36, 46) are smoothly operated within the connection channels (24, 24′).</p> |
