* In certain applications, deadband can be tailored and controlled to customer specifications. Consult factory for details.
** Operation of both switches in most cases will not be simultaneously, but will occur within the specifications listed. Deadband figures already reflect the improvement from the -RD option which is automatically included in the -AA, -BB, and -CC circuits.
