Is this an APU switch?

[fordgt40]

I recently bought this switch, which was advertised as a 737 APU switch. It has only two positions, one spring loaded. There are two separate connections for a 28volt dc coil. The notation on the casing is 5ET1-S  6945. I have queried this with the vendor suggesting that it is NOT a 737 300-500 or NG switch, more likely a A/T switch. Can anyone here advise?

Indeed not a 737NG APU switch (also not CL afaik)
You can use this switch wherever there's a solenoid switch used though. Yaw damper, voice recorder or as some people use as a wing anti ice switch (the real WAI is a circuit breaker not a solenoid switch)

Hi Jeffery, many thanks for that.
Before I go back to the vendor shouting foul, I assume that it is also not an earlier 737 eg 737 200?

Thanks
