How a Hook Switch Works

A hook switch is like a smaller, smarter version of a handset lifter. It is an electronic switch that connects between your handset and your headset base station. When you press the appropriate button on your headset it sends a signal to your phone to answer or hang up on a call. This means you can now start or end conversations from anywhere in the office using your wireless headset, without having to return to your desk.
Unlike a handset lifter, a hook switch contains no moving parts which means they answer/leave calls much quicker than a lifter, and are also theoretically more reliable. However not all hook switches work with all phones, so make sure you choose the right model to work with your handset.
