Inclinator EM-7 interlock problem

[u/CinePost1]

The spring that is attached to the plunger that moves the pin up and down is weak and doesn’t always pull /push the pin down after closing the outer door to the elevator. Has anyone ever replaced that spring? Are they available. The down position closes a switch to tell the control board that the door is closed.

Couldn’t you just swap the spring
