Hacking of systems attached to hub is complex. While switch is very sophisticated device and widely used. Hub is simply old type of device and is not generally used. While switch is an intelligent device that sends message to selected destination so it is expensive. Hub is not an intelligent device that sends message to all ports hence it is comparatively inexpensive.
While in switch, Packet filtering is provided. In hub, Packet filtering is not provided. While switch is a full duplex transmission mode. While in switch, different ports have own collision domain. In hub, there is only one collision domain. While switch is a Unicast, multicast and broadcast type transmission. While switch is operated on Data link layer of OSI Model. Hub is operated on Physical layer of OSI model.

THERE IS NO BULKY RELAY BOX with our kit, as we utilize technology that allows us to control each circuit with a microprocessor. It has a 3”圆” footprint and comes with a fused power cable, and both harnesses which communicate with the touch panel. It is COMPLETELY SEALED, and rated to 125 degrees Celsius. The kit also includes 100 switch legend options, so you can customize the panel to your specific accessory set up The under-hood mounted power module is waterproof, and ideal for all applications. RGB technology allows you to choose ANY backlighting color you desire. Programming options include output Dimming, Strobing, Flashing, Master-Slave functions Memory, Auto Power-Up, Momentary, Battery/Ignition input, and a multitude of other options. The panel includes a Bluetooth transmitter, which allows you to program AND operate your system from any wireless device. The touch panel is weather resistant, and measures only 2”x4”. With a total of eight circuits, four rated at 20 amps each and four rated at 35 amps each, you can power all types of 12 volt accessories. The Switch-Pros SP9100 is a compact, solid state switch panel power system, capable of flowing 125 amps of continuous power.
