Vszerda USB On/Off Switch Cable 28AWG 3.3ft 2-Pack

USB on/off switch cable for low-power peripherals

This two-pack provides USB cables with an integrated toggle that controls both data and power. Each cable uses 28AWG wiring and measures 3.3 ft in total length, with 2.48 ft from the male plug to the switch and .36 ft from the switch to the female port. The switch connects the circuit when pressed to the marked side and disconnects it on the unmarked side. Rated for 5 V at up to 2 A, the cables suit USB fans, LED desk lamps, wireless headsets, microphones and similar low-power devices.

Check port version and device power draw

The cables operate at USB 2.0 speeds even when plugged into USB 3.0 or newer ports, so high-bandwidth peripherals will not run at their rated throughput. They cannot support high-power electrical devices, so confirm the connected accessory stays within the 5 V, 2 A limit. Ensure the host port can supply enough current for the peripheral and that a physical on/off toggle at the cable is preferred over software control.

Replaces always-on USB extension cables

These cables upgrade from standard extensions by adding a hardware switch that cuts power and data without unplugging. The jump is worth it when you regularly disable a desk lamp, fan or headset and want to avoid wear on the port or the device’s own connector. They are not for users who need USB 3.0 or higher data rates, nor for charging phones, tablets or other devices that draw more than 2 A.
