An A/B switch is a mechanical selector device that allows you to choose which signal source your TV uses at any given time. Examples of TV signal sources include the coaxial cable through which you receive Alameda Power & Telecom service, as well as "rabbit-ears", roof-top antennas, etc. You may also find an A/B switch useful for connecting a home video-game system, or for advanced TV viewing options, such as watching one channel while recording another.

At your request, we will sell and/or install A/B switches for you on any TV in your home that is connected to our cable service for the cost of equipment and at our hourly service rate. You may also choose to purchase and install A/B switches yourself. If you request Alameda Power & Telecom to make an A/B switch connection to an outdoor antenna, that antenna must be operational and installed in accordance with all applicable laws, rules, codes, and regulations, including those requiring grounding.
