SMUGDESK

SMUGDESK USB-C Male to Female Extension Cable with On/Off Switch

SKU CH-W5HF-P5A7F

USB-C extension cable with built-in on/off power switch for convenient device control without unplugging

  • Independent on/off power switch cuts power without unplugging
  • USB-C male-to-female extension adds flexible reach for devices
  • Stable power and signal delivery for Raspberry Pi 4B and peripherals
  • Reinforced strain-relief joints prevent wire breakage from bending
  • Plug-and-play operation requires no drivers for DIY setups

USB-C Extension Cable with Power Switch

This USB-C male to female extension cable adds a physical on-off switch so you can cut power to a connected device without unplugging it. The design suits Raspberry Pi 4B units, USB-C laptops, mechanical keyboards, hubs, cameras and other Type-C powered peripherals. It is a practical accessory for DIY electronics projects, desktop wiring management and office equipment setups.

Thermals Noise and Power Draw

The cable uses oxygen-free copper conductors for low resistance and steady current delivery during normal operation. No active cooling or fan is present, so the product runs silently and adds negligible heat to the system. Power draw is limited to the attached device and the switch itself introduces no measurable overhead.

Reinforced Strain Relief and Switch Integration

Both ends feature reinforced strain relief to resist wire fracture from repeated bending and pulling in daily use. The compact switch module is moulded into the cable body, staying secure and easy to operate over time. This construction reduces wear on device ports and supports frequent power cycling without mechanical failure.

Questions about this item

How do I install the SMUGDESK USB-C extension cable with the on/off switch, and what is the common mistake to avoid?

Connect the USB-C male plug to your host device and the female end to your peripheral. The common mistake is forgetting to toggle the inline switch to the ON position after connecting, which leaves the device unpowered.

What maintenance or replacement will the SMUGDESK USB-C extension cable need over time?

The reinforced strain relief joints resist bending fatigue, but inspect the cable periodically for sheath damage or intermittent connectivity. Replace the cable if the switch becomes loose or power delivery becomes unstable.

What limit appears first when using the SMUGDESK USB-C extension cable continuously with a Raspberry Pi 4B?

The inline power switch and cable assembly are rated for standard USB-C power delivery; sustained maximum current draw may cause the switch module to warm up, signalling the thermal limit of the compact housing.
