HSH1. Five positions, no Humbucker splitting, Megaswitch S
This is the simplest switching system for guitars with two Humbuckers and a single coil located between them. Here, the Humbuckers are not split and the switching functions are as usual. The Megaswitch S is ideal for this application. A version with two tone controls is illustrated. If only one is to be used, the wiper should be connected to connection 4 of the Megaswitch.
If you want to use this circuit in a guitar with only one tone control, then connect this to the right stop of the volume control (or contacts 4 and 8 on the Megaswitch S).

HSH2. Five positions with Humbucker splitting, inner coils, Megaswitch S
This switching system is for guitars with 2 Humbuckers and a single coil between them. The Humbuckers are split in positions 2 and 4, while the inner coils remain active. The outer coils are short-circuited. In the event that a buzz-free sound is required in positions 1, 2, 4 and 5, the following magnetic polarity is required: NS-N-SN or SN-S-NS. The Megaswitch S is ideal for this application. A version with two tone contols is illustrated here. If only one tone control is used, its wiper should be connected to connection 4 of the Megaswitch.
If you want to use this circuit in a guitar with only one tone control, then connect this to the right stop of the volume control (or contact 4 on the Megaswitch S)

HSH3. Five positions with Humbucker splitting, outer coils, Megaswitch S
This switching system is for guitars with 2 Humbuckers and a single coil between them. The Humbuckers are split in positions 2 and 4.Contrary to the HSH2, the outer coils remain active and the inner coils are short-circuited. In the event that a buzz-free sound is required in positions 1, 2, 4 and 5, the following magnetic polarity is required: NS-S-SN or SN-N-NS. The Megaswitch S is ideal for this application. The outer coils are short-circuited. In the event that a buzz-free sound is required in positions 1, 2, 4 and 5, the following magnetic polarity is required: NS-N-SN or SN-S-NS. The Megaswitch S is ideal for this application. A version with two tone controls is illustrated here. If only one tone control is used, its wiper should be connected to connection 4 of the Megaswitch.

HSH4. Five positions with Humbucker splitting in positions 2, 3 and 4, Megaswitch E
This is a variation of the HSH3 switchng system. The positions 1, 2, 4 and 5 are as usual and in position 3, the inner coil of the bridge Humbucker and the outer coil of the neck Humbucker are switched parallel. This results in sounds that are similar to a Telecaster, when both pickups are in operating mode. A buzz-free sound can be obtained in all positions; the following magnetic polarity is required - NS-S-SN or SN-N-NS. Here, Megaswitch E is in use.
If you have a guitar with two tone controls (type "Stratocaster"), then just leave one unused.

HSH5. Five positions with Humbucker splitting in positions 2 and 4, Megaswitch E+
This is a variation of the HSH4 switching system. The positions 1, 2, 4 and 5 are as usual and in position 3, both Humbuckers are switched parallel. This results in a fuller, louder sound than splitting. A buzz-free sound can be obtained in all positions; the following magnetic polarity is required - NS-S-SN or SN-N-NS. The Megaswitch E+ is ideal for this purpose.
If you have a guitar with two tone controls (type "Stratocaster"), then just leave one unused.

HSH6. Five positions with Humbucker splitting in positions 2, 3 and 4, Megaswitch M
In this switching system two coils are connected in series at a time. All positions are free of hum when the magnetic polarity is NS-S-SN or SN-N-NS. Here a Megaswitch M is in use.
If you have a guitar with two tone controls (type "Stratocaster"), then just leave one unused.
