Example of the parts to order to build a complete GS or LK switch:

For example:

LK3SU3 (600 A nonfusible switch, use 15x15 shaft)
+ GS1AE6 (15x15 200 mm Type H shaft)
+ LK3AH150 (black/black, lockable)

To add auxiliary contacts:

For front-mounted contacts order
GS1AD30 (front-mounted auxiliary contact holder)
+ GS1AM110 (NO contact for GS1AD10, 20, 30)
