Working on the Dover Composite Traction Elevator 1970's. I have drawings T2530, T3091 & T2244. Not sure which set is right. Dover's archives weren't readable. I'm looking for the schematic for the shaft doors closed interlocking/latching switches that you use the through hole tool to open the shaft outside door. These switches are located in the top corner of the shaft door on the closed side. My customer has had a couple incidences with the elevator not operating because one of the shaft doors has failed to fully close and close the contacts. I'm looking for the circuit these 4 door switches are used in so I might be able to attach an LED to show the customer which door is the issue. Thanks
