Installation & Adjustment Procedures 

5.  Place counterbalance arm directly on the other bearing hub and other intrapole arm on top.  Be 

certain the angle between the two arms is set correctly.  Bolt insulators directly to the intrapole 

arm plate. 

NOTE:  Field assembly of switches with multiple unit insulator stacks is easier when the lowest unit is 

mounted first and balance of units mounted to it rather than mount the entire stack as a single unit. 

6.  Rotate insulator with switch arm clockwise (facing down) against the stop and attach intrapole 

linkage.  Be sure length of this linkage is properly set to dimension shown on drawing.

 

7.  Depending upon its application, this type switch will be counterbalanced either by weight or by 

spring.  Refer to unit assembly drawing and attach appropriate number of weights – or the 

spring – to the counterbalance.

 

8.  On top of stack with the switch arm only, securely bolt the male blade assembly in line with 

length of the base.

 

9.  On the other stack, securely bolt the female blade assembly.  The switch will have to be 

opened slightly to do this.

 

Contact Misalignments 

 

Check for proper blade alignment.  The blade segments should meet on centerline of base, on center of 

each other and the stop plug centered and touching (not jamming) the male contact stirrup (

Figure 3

)

 

 

Figure 3: Proper Contact Alignment 

 

There are three general types of blade misalignments correctable by jack screws and two correctable by 

linkage adjustments. 

 

Field Assembly Note:

  Due to probable insulator stack deflection caused by conductor loads, the 

following adjustments can be “rough” adjustments but not considered final adjustment until the 

conductors are attached to both ends of the switch. 

 

IMPORTANT:

  When adjusting jack screws, adjust each pair of jack screws equally (count the flats).  

This is to ensure the insulators will move along the centerline of the base in a straight line.  See 

Figure
