A two in, one out switch controlled by the DiSEqC protocol.

A typical application is the switching of 2 universal LNBs, where the
receiver's 13/18V and 22KHz tone is used to control the LNB, and DiSEqC
controls the switch. Both full and mini DiSEqC protocols are supported.
The switch, in a screened metal box, (sat & dc switches only) are
enclosed in a rain proof plastic cover that protects the switch and the
three connectors. This avoids the need for time consuming and
expensive tape or boots.

Dis-2x1-sat & Dis-2x1-wb are able to be reconfigured so as to enable
cascading.
