PROBLEM TO BE SOLVED: To provide a switch gear in which a switch is located near a dial type operator and which can prevent an improper operation of the switch.SOLUTION: A switch gear includes: a dial type operator D operated by a manipulator; a first proximity sensor 11 which is located near the operator D and detects operation for the operator D; a second proximity sensor 12 which is located at a position further separated from the operator D than the first proximity sensor 11; a third proximity sensor 13 which is located at a position further separated from the operator D than the second proximity sensor 12; and a signal processing part which processes a signal inputted from the first proximity sensor 11, the second proximity sensor 12 and the third proximity sensor 13. The second proximity sensor 12 and the third proximity sensor 13 are located in a switch display area A2 in which one switch S2, which accepts operation by the manipulator, is displayed.SELECTED DRAWING: Figure 1 |
