CHAPTER 2: Introduction
2. Introduction
Switching between data lines manually can often damage the connected
equipment, because this relatively slow and imprecise action can cause data-line
surges and spikes large enough to damage today’s sensitive circuitry. With the
Local/Remote Electronic Switches, you can eliminate this potential hazard. Their
electronic switching action provides surgeless, spikeless changeovers—something
a mechanical switch just can’t do.
In addition, these switches can be controlled remotely, from a convenient
out-of-sight location.
The stock models available are:
SW980A 115-VAC 2-to-1 Switch
SW980AE 230-VAC 2-to-1 Switch
SW981A 115-VAC “X” (2-to-2) Switch
SW981AE 230-VAC “X” (2-to-2) Switch
SW982A 115-VAC 4-to-1 Switch
SW982AE 230-VAC 4-to-1 Switch
These Switches can also be cascaded to allow a larger number of ports
to be switched.
