1987779-1

TThe 1987779-1 application field and working principle is a device used to switch between many input sources and one output source, allowing for simultaneous control of multiple devices. It is commonly used to switch between TV signals, stereos, dictaphone recordings, or other sources of audio or video sources. The 1987779-1 also provides the means to switch between several output sources, such as amplifiers or other audio output devices.

Technically speaking, the 1987779-1 is a mechanical device composed of an input selector, a switch, and an output selector. The input selector is a bank of contacts which can be manually engaged and disengaged from the input source. The switch is a device which engages and disengages the input contacts from the output selector. The output selector is a bank of contacts which can be bound to different output parts, such as the amplifier, audio out, TV out, etc.

The 1987779-1 operates by providing a signal from a single input source to the switch. This signal is then sent to the output selector, which is also connected to a multitude of different outputs. By adjusting the switch, the user can select which output the signal should be routed to. The 1987779-1 also provides the ability to have the switch engaged and disengaged from the output selector at the same time, allowing for simultaneous control of multiple devices.

This device is particularly helpful when used with multiple pieces of audio or video equipment, since it allows for seamless switching between different sources and outputs. Furthermore, since the 1987779-1 is a mechanical device, it is able to operate without the use of a computer or other digital control devices.

The 1987779-1 can also be used to control multiple devices from a single point of control. For example, when used with a television set, it can be used to switch between different television channels. In addition, this device can be used to switch between different sources of audio, allowing for a more convenient listening experience. Finally, it can be used to switch between different outputs, such as TV or stereos.

In summary, the 1987779-1 is a useful device for controlling multiple devices from a single point of control. It is a mechanical device composed of an input selector, a switch, and an output selector. It operates by providing a signal from a single input source to the switch, and then sending this signal to the different output devices. It can be used with televisions, stereos, dictaphone recordings, and more, allowing for seamless switching between different sources and outputs.
