It switchs respective contact to be arranged in the movement routine of indicating arm, so that referring to when the first moving contact is engaged with the first static contact
Show that the lower edge of bar presses the contact of the first microswitch, to connect the first microswitch, electrically indicates that the first power supply connects
Logical position, when the second moving contact is engaged with the second static contact, the lower edge of indicating arm presses the contact of the second microswitch, from
And the second microswitch is connected, electrically indicate second source on-position.
12. position indicator as claimed in claim 10, which is characterized in that the lower part of the indicating arm have a groove, one
Pivotal part is pivotally disposed in rack, and when indicating arm is moved along first direction or second direction, groove can be with pivot
One stabilizer blade of part engages, and pivotal part can be made to pivot, thus the contact of the first microswitch of pressing or the second microswitch, into
The electrical instruction of the position of row dual-power transfer switch.
13. a kind of dual-power transfer switch, including position indicator as described in any one of the preceding claims.
