The Data Bus relay/switches family of products are typically used to switch MIL-STD 1553 signals between Bus A and Bus B. The switching is accomplished without the interuption of databus protocol.

The DBPR2000 series can switch a UUT from one bus to another (typically A to B) with switching to as many as four buses possible. The device is also used to segement an existing bus into smaller sections. This is useful when adding/removing 1760 stores management systems devices to the bus."

"The DBPR1000 is used to shorten an existing bus at some "break point". It will switch to an off position without creating an open circuit impedance."
