MH Battery switch
I have a bad coil 120-105452-6 and have a replacement 120-105752-6 bith made by white rogers and need to know if they are interchangeble. White Rogers says they have no info. Need help.

They are compatible (and interchangeable) with respect to all operating characteristics.
Current capabilities of the coils are identical.
Current capabilities of the contacts are identical.
Contact material (silver alloy) is identical.
Mounting bracket may be slightly different. (no big thing)
What IS different, are the small coil terminals.
The 105452 has either just a single terminal (with the other end of the coil grounded internally) or two terminals with one of the terminals externally grounded to the mounting bracket to provide the path to ground.
The 105752 has two isolated terminals for the pick coil. You will need to connect one terminal to your 12V pick signal and then connect the other to ground. If they are polarity sensitive, they will be marked.
