Detailed description of the invention
The switch of 1 to Fig. 4 chopper a kind of to this utility model interlocking mechanism opens and closes referring to the drawings
Error prevention device is described in further details.
The switch of a kind of chopper interlocking mechanism opens and closes error prevention device, including frame 1 and setting
For controlling disconnecting switch and the opening/closing component 2 of earthed switch keying in frame 1；
Described opening/closing component 2 include operate axle 21, operation panel 22 and open and close slide plate 23 and
Order about open and close slide plate 23 reset back-moving spring 24, the one end of described operation axle 21 with every
Leaving pass or earthed switch is connected, the other end is placed in operation panel 22 and is provided with handle hole 221
On, the described relative operation panel 22 of keying slide plate 23 slides up and down, for opening or closing behaviour
