Piezo Buzzers

These days there are few electronic products we wear, click or talk to that don’t have a piezo buzzer, magnetic vibrator or haptic indicator on board. Our Piezo and Magnetic Buzzer range offers easy interface audio indicators as well as more complex audio transducers you can create your own unique sounds with. Looking for a buzzer in a custom size or style? RDI has you covered there too.

Wireless Charging Coils

RDI's Wireless Charging Receiver coils are manufactured with High Permeability shielding to help mitigate external interference from permanent magnets and local sources of EMI. Choose one of our 12uH coils or let us manufacture devices to your custom specifications of inductance, wire gauge, shielding and mechanical attachment requirements.


Our excellent range of switch styles, types and mounts is made even better by our ability to customize any switch to your own requirements. Search through our comprehensive list of products to find the right switch for your application.
