These old school custom built devices used a hand built radial sequencer to operate each of the lights and two tone chimes. A Hanson 600 series Synchron motor was used to drive the sequencer, and three single pole double throw relays were used to control the operation. Everything can still be purchased except the custom-built radial sequencer. This sequencer is built up from a LE grade linen phenolic ¼” thick board, with two rows of electrical contacts. This appears to be arranged as a twelve position radial switch, non-shorting, each at 30 degrees. The outer row is flat top button contacts for the lights, and the inner row is narrow diameter pin contacts for the chime. As an item of interest, the L1 - 120 volt AC and the 16 volt AC for the chimes are both connected to the same central wiper.
My question for the group is that I am looking for a “company” that sells the contact and wiper parts that would be installed into the linen phenolic board of this old school live face, switch gear. FYI – If a modern PLC were to be used to duplicate operation, it would need at least 1 digital input to start ritual sequence and 13 digital outputs, where two of the DO’s would need to operate at the chimes voltage of 16 volt AC and the other eleven would need to operate at 120 volt AC.
So, once again my question relates to the availability of manufacturing old school live face panel boards. I have seen old school live face panel boards at power stations that have radial tap switches for step up transformers.
I suppose it is possible to make a business out of this kind of thing and I am sure your county would want you to get a license (AKA business tax receipt). I would think of it as a hobby tho, until you found enough customers to call it a business. I do understand the urge to bring old stuff back to life tho. I have a bit of that myself. Like any business, your first problem is connecting with your customers.
