<P>PROBLEM TO BE SOLVED: To provide an electric point-switch which facilitates setting of the conversion direction and the display direction and which is low-cost. <P>SOLUTION: Conversion control units 211, 221 perform a fixed position operation and the second fixed operation corresponding to the polarity of a control power source. Changing units 212, 222 include switch units SA, SB, control power source input terminals T10-T40, and display output terminals T50, T60. The switch units SA, SB perform the switching operation between the first switch state in which the control power source input terminals T10-T40, and display output terminals T50, T60 are connected to the conversion control units 211, 221 as they are, and the second switch state in which the polarity is inverted from the first switch state, and connection is executed to the conversion control units 211, 221. <P>COPYRIGHT: (C)2012,JPO&INPIT |
