Quick Answer / Summary: Per-port switches cut power (and data, on some builds) individually: the sticky-flash-drive desk reboots one port instead of the hub; sync/charge switches route amps without data. The 6-port form: the switched class’s sweet spot (4 is sparse, 7 strains budgets). Lines: switch class (power-only vs sync/charge), per-port LED honesty, brick wattage (6 ports want 30W-class), and switch quality (the toggle that survives ten thousand cycles).
The per-port switch is the hub’s most under-specified feature – and the 6-port switched form is where it earns its keep: six devices, individual control, the desk’s sticky-note chaos tamed. This guide reads the switched class properly.
What the Switches Actually Switch
Two switch classes hide under one word: power-only switches (cut the port’s VBUS – the device powers off, data lines stay idle; the stuck-device reset and the phantom-power killer) and sync/charge switches (route the port between data mode and charge-only mode – the phone that charges fast without enumerating, the device that must not talk to the computer). The class difference reads in the listing’s phrasing: ‘individual on/off switches’ is power-class; ‘sync/charge switches’ is the dual-mode class. The duty picks: the reboot-a-frozen-flash-drive desk wants power-class; the charge-my-phone-without-syncing office wants dual-mode. The 6-port switched hub that states its class is the honest buy.
The Frozen-Drive Reset
The flash drive that wedged the Explorer: power-cycle the port (the switch), not the whole desk. The switch’s flagship micro-job – and the reason power-class switches sell.
The 6-Port Economics
The 6-port count: the switched class’s sweet spot – four is sparse once switches eat desk planning (two ports ‘reserved’ as the reset pair), seven strains the brick’s honest wattage (35W-class for full per-port integrity). Six ports at 30W-class brick: every port full data budget, the switch matrix accounted, the price landing at $25-40. The layout line: switches per port (not bank-switched – the 3-bank ‘switched’ hub switches pairs, the listing’s fine print that the photos reveal), and the switch placement (accessible top edge, not the rear where the cable forest lives). The 6-port form’s economics price the class’s honest construction.
The Bank-Switch Fine Print
‘Switchable’ hubs that switch banks of two: the photo shows six switches, the spec says three. The per-port vs bank distinction is the class’s most common listing trap.
The Switched-Hub Checklist
The lines: switch class stated (power-only or sync/charge), per-port switching confirmed (against the bank-switch fine print), LED per port (the switch state visible), brick wattage (30W-class at six ports), and switch quality (the toggle rated for the desk’s decade – the ten-thousand-cycle spec where stated, the feel test where not). The verification: switch each port off-on (every port returns), benchmark under all-on (the 30W budget holds), and charge-test the dual-mode ports if present. The switched hub verified is the desk’s control panel; the unverified one is the drawer’s next ‘why is port four dead’ mystery.
The Toggle Feel Test
The desk’s switches get toggled daily for years: the crisp toggle survives; the mushy one dies by month six. The feel test on arrival is the spec where the cycle rating isn’t printed.
Switched Hub Classes
| Class | What Switches | Right Duty | Price |
|---|---|---|---|
| Power-only | Port VBUS | Frozen-device resets, phantom power | $20-30 |
| Sync/charge | Data vs charge routing | Phones charge without sync | $25-40 |
| Bank-switched | Pairs of ports | n/a – read the fine print | $15-25 |
| 6-port honest build | Per-port, class stated | Control-panel desks | $25-40 |
Real-World Application Scenarios
A test lab’s bench hub: power-class switches reset wedged dongles daily – the reset pair ritual, zero reboots. An office’s charge-desk hub routes phones to charge-only ports – the sync-policy line enforced by hardware. A photographer’s 6-port switched unit powers card readers individually – the dead reader identified by its LED, not by unplugging everything.

Frequently Asked Questions (FAQ)
Q: Do the switches cut data too, or just power?
A: Class-dependent: power-only switches cut VBUS; sync/charge switches route data vs charge. The listing’s phrasing names the class – read it.
Q: Why does my ‘6-switch’ hub switch ports in pairs?
A: Bank switching – three switches for six ports. The fine print and the photos reveal it; per-port builds state ‘individual’ switching.
Q: What brick does a 6-port switched hub need?
A: 30W-class minimum for full per-port budgets. The shortcut tier ships less and throttles under load – the wattage number is the line.
