Essentually none. Toneburst 22KHz speaks to the tone or command given from the receiver to the switch. 22KHz switch is just that - the switch 0KHz or 22KHz.

Exactly how it sounds, a tone burst is a 22 KHz tone of a certain length to control a switch, LNB or motor, it can burst in a binary fashion "ON OFF OFF ON ON ON OFF ON" to be a "10011101" to give a command code to turn something on or off.

A 22 KHz switch has the tone on all the time for one port and off all the time for the other, 22 KHz on = satellite LNB A, 22 KHz off = satellite LNB B.
