ACCESSORIES
Auxiliary Switch (KA102GV1)
The auxiliary switch, mounted to the top of the operator
cabinet, in a weather-proof housing, is used for relaying or
interlocking schemes and for remote contact indication.
Two switch stages are provided. Each stage consists of
two independent contact assemblies with either “a” (nor-
mally open) or “b” (normally closed) contacts which can
be easily changed in the field. A data plate attached to
the switch cover shows the switch arrangement. Related
switch contact positions are shown in Table 5.
The switch is permanently wired to a multi-pin receptacle
in the bottom of the mechanism operator cabinet. Table 6
shows the pin arrangement of the the mating plug shown
in Figure 12.
The switch contacts are insulated for 600 volts and have a
continuous current rating of 10 amps. Their interrupting rat-
ings are shown in Table 7.
Switching positions can be changed from “a” or “b” opera-
tion by repositioning the cams inside each switch section.
To change any cam position:
1. Remove the auxiliary switch cover.
2. Detach the switch from the switch link by removing the
groove pin and C-rings.
3. Remove the machine screws attaching the assembly
to the cabinet.
4. With the switch removed, unfasten the two hex nuts
and lockwashers from the long machine screws that
hold the switch sections together.
5. Starting with the rear switch section, lift the cams off
the operating shaft, replacing the cams in one of the
positions shown in Figure 13.
6. Reassemble the switch sections, as removed, and
remount the switch on the sectionalizer.
