For example, in an Adams Car suspension template, you may want to connect the drop-link of an anti-roll bar (stabar) to either a suspension A-arm or the suspension upright (a damper in the context of a MacPherson strut). In this case, you would connect a spherical joint between the end of the drop-link and A-arm or suspension upright. By connecting either the I or J marker of the spherical joint to a switch part and adding A-arm and upright to the parts list of the switch part, you enable the drop-link to be connected to either the A-arm or the upright.
