I need someone to design a small circuit board that has integrated rotary dimmer-(click) off switch to dim and turn off a 12V halogen bulb. The circuit board + components must be able to fit inside a 10mm (internal diameter) tube. 12V supply wires will come in one end and output wires will leave the other end. The dimmer must click off ie. no leakage in off position. The angular rotation of the dimmer should not be more than 90 degrees from click on to full output voltage.
The whole arrangement must be electrically insulated within the 10mm thickness without overheating. The rotary actuator for the dimmer should have its rotation axis parallel to the length of the board.
Please see attached for a rough idea of what I am looking for.
I would like CAD drawings of both the circuit board design and total component with component references
I would like a Parts list for components with reference numbers for a UK component supplier (RS preferred)
I would like electrical specs eg. min-max input voltage,current etc. , min-max output voltage, current, wattage, operating temperature range.
