Bose QC35 Power Switch Board PCB: Restore Your Headset’s Logic

Is your Bose QC35 or QC35 II refusing to power on, or does it stay on even when the switch is in the ‘off’ position? Internal power board failure is a common issue often caused by liquid ingress or the micro-switch breaking away from the PCB. This Grade A Genuine replacement Power Switch Board is a 10/10 condition salvaged OEM part, designed to restore reliable power management and Bluetooth pairing functions.

At Fix Headphones, we specialise in providing genuine salvaged electronics. Unlike unverified third-party boards that can cause parasitic battery drain or connectivity drops, our original OEM parts maintain the high standards Bose is known for, while supporting the UK’s Right to Repair.

Technical Specifications & Installation

• Part Type: Internal Power Switch Logic PCB.
• Condition: Grade A (10/10 Salvaged OEM).
• Compatibility: Fits Bose QC35 and QC35 II models.
