Need some help Identifying a SWF 3-Wire Turn Signal Switch

[olivetree]

I need some help identifying the original application for this 3-wire SWF turn signal switch. The part number shown in the turn signal housing is SWF HLS10/51. Its an original 3-wire switch rather than the normal 6-wire configuration that you would find in a North American Oval.
I was wondering if it can be used on a European Spec Oval with Semaphores since its the 3-wire. My concern is that the wires seem fairly thin gauge and don't look like the can handle the 8 amp load that a 6 volt semaphore solenoid would draw.
Any help with this would be appreciated. I've included some photos of the switch.

Not sure of its application but not a semaphore switch.

for a vw bus?

I think it’s a semaphore switch in a six wire housing.

I appreciate those that have provided their help in identifying this switch. I found some information online that suggests that this 3-wire configuration turn switch was used on buses that had separate rear turn signal and brake lights so the switch may have been used to only power flashing left and right turn indicators.

I have read and have been told that this 3-wire turn switch can't be used to operate semaphores. I've looked at the wiring diagrams for both European and North American 1954-1957 Ovals and while the wiring diagrams show a 3-wire "Semaphore" turn switch on the European Oval and the typical 6-wire turn switch for the NA Oval, its interesting to note that the wiring diagrams show the same metric size 1.0 (mm2) wire connected to both switch types. The metric wire size translates to an AWG number somewhere 16 (1.31) and 18 (0.823).

Based on the fact that both switch types use the same wire gauge, I would assume that this black 3-wire turn signal switch can be used to operate Semaphores. The Semaphore solenoid coils draw 6 Amps of power which is within the power handling capabilities of a metric size 1.0 wire.

So other than it not being "correct" or "original" to use a non-semaphore 3-way switch like this one in a Semaphore equipped car, is there any other technical reason as to why I shouldn't use this switch for my custom Semaphore, front and rear blinking LED turn signal setup with Chip's LED Snowflake rear lights on my 1957 Oval?

I'm asking this question because as the old saying goes, I don't know what I don't know.
