WANTED: WECO #6 operator dial.

Is that the 20 PPS dial (#6E) or a standard 10 PPS #6 dial?

It is one that would go on the WECO 555 PBX I recently got.

Thank you for the info on the lamp extractor. I was hoping to get one cheaper from a fellow collector.

6E is 10 PPS. "For PBX and central office switchboards for local and intertoll dialing."

6F is 20 PPS.  "For PBX and central office switchboards arranged for high-speed dialing."

6G is 20 PPS. "For 555-type switchboards."

I believe all 3 of these have the same wide finger stops. 20 PPS dials should be used only where the trunk (2-way telephone line) can recognize 20 PPS.

However, the contact spring pileup on the 6G is the same as a 6A (found on 302s, etc.), 6C (on pay phones) or 6D (color 302s).

David, thanks. That's what I get for trying to read replies at 3 in the morning. unbeldi posted F and I saw and typed E.

IIRC, only the 20 PPS dials had a finger stop that was not flat, was curved or cut down to fit the finger to as to what, not create a sharp edge and callous or cut the operator's finger?

Still interested in which one Fabius needs, a 10 PPS or 20 PPS. Those 20 PPS dials sell for cheap on eBay when they come up - nobody seems to want them.

The 6E dial is inappropriate for a dial telephone, not only because of the finger stop, but it is lacking the proper number of off-normal contacts for a dial telephone set.

It is perfect for a switchboard, incl. the 555.

Here is the switch configuration of the 6E:

Neither the 6E nor the 6F is appropriate for a 555 PBX. Neither has the correct configuration.

6A would be OK, but would not have the special finger stop.  From the cited BSP C18.005 i4, 6G is specified [for 20 PPS], which has the same pileup as a 6A.

SD-66520-01-B4, Fig. 8 (TCI library)  shows "5H, 6A or 6R-3" for Option Y and "5KB or 6G-3" for Option Z.

6g it is then. Thanks.

You are correct.

6G could have been used with #5 Crossbar Central Offices, but it would be too fast for Step-by-Step Offices.
What kind of line will you be using as a trunk for the 555?
