Product Line:

Cause:
Product features

Resolution:
Both items are 3 position, momentary or spring return from both sides selector switches. Both
have 2 - 9001KA1 contact blocks but have different cams. The cams will determine the contact
configuration by allowing the contacts to open and close differently. Since the cams can be ordered as a repair part,
many incorrect selections can be resolved by simply replacing the incorrect cam with the the correct one.

The 9001KS52BH2 has a "B" cam and the contact configuration is as follows:
1 0 0
0 1 1
0 0 1
1 1 0

The 9001KS53BH2 has a "C" cam and the contact configuration is as follows:
1 0 0
