Fervit DC Switch Cable 5.5x2.1mm Male to Female

This inline power switch cable connects devices with a 5.5x2.1mm DC barrel jack. It carries only DC power at 5V or 12V and does not transmit USB data. The built-in button lets you toggle power without unplugging the connector. It is intended for low-power peripherals such as LED lamps, small fans or similar 5.5x2.1mm equipment.

Installation and common issues

Plug the male end into your power source and the female end into the device, then press the button to switch power on or off. The cable supports only low-power loads and cannot be used with high-power equipment or PD chargers. Because it lacks data lines, it will not work for devices that require USB communication. Forcing it into an incompatible port may damage the connector.

Compatibility check before ordering

Verify that both your power supply and the target device use a 5.5mm outer diameter and 2.1mm inner diameter barrel connector. Confirm the device operates at 5V or 12V and draws only a low current suitable for a two-core charging cable. Ensure you do not need USB data transfer or fast-charging protocols, as this cable provides neither.

Questions about this item

How do I confirm the switch is controlling power to my DC 5.5x2.1mm device after connecting it?

Press the on/off button and verify the connected device powers on or off immediately; the cable passes only DC power at 5V or 12V with no data lines.

What comes in the package and what must I provide separately?

The package includes the Fervit DC switch cable with 5.5x2.1mm male and female ends; you must supply a compatible DC power source and a device with a matching 5.5x2.1mm input.

Which voltage version should I select for a 5V desk lamp versus a 12V fan?

The same cable handles both 5V and 12V low-power devices; choose it if your lamp or fan uses a 5.5x2.1mm jack and draws within the supported range.
