AKG 9040E00100 - Power Switch for the AKG HT 450 Handheld Wireless Transmitter

AKG 9040E00100 - Power Switch for HT450 (WMS450) Handheld Wireless Transmitter

The AKG 9040E00100 is the original power switch used on the AKG HT450 WMS450 series handheld transmitter. It is an OEM replacement part that replaces the original power switch when it fails (no power on, intermittent cut-outs when the selector is moved, etc.), restoring reliable operation of the handheld microphone's power control. As the manufacturer-specified replacement, it guarantees mechanical and electrical compatibility with all HT450 variants (e.g., those with C5 or D5 capsules), maintaining the factory-installed performance of the system.

It is installed on the HT450's circuit board and may require soldering and adjustment , so it is recommended that it be replaced by qualified personnel. If, in addition to the electrical switch, you need the external part that slides with your finger, AKG offers the HT450-specific "Actuator Slider Switch" as a separate replacement.
