<human>:  What is the difference between a splitter and a HDMI switch?
<bot>: The main difference between a splitter and a HDMI switch is that a HDMI splitter divides a single source signal into multiple outputs, while a HDMI switch allows multiple HDMI signals to be routed to a single display device, such as a television. A HDMI splitter is typically used to connect one source device, such as a Blu-Ray player, to multiple display devices, while a HDMI switch is used to connect multiple source devices to a single display device.
