DIY stepped attenuator using C7D0423N rotary switch.

[binspaul]

Hi,

I am planning to design a stepped attenuator based on the C7D0423N rotary switch available from Electro Switch. It is a 4 deck switch having 23 positions. I am not sure on the method to identify the terminals and the method to connect the resistors. Can someone suggest me a method I should follow.

I am attaching the C7D0423N manual along with the resistor tables for reference.

Thanks in advance,
Bins.

Hi,

Few more details... The attenuator will be of ladder type. All the resistors are Dale RN60D.

Best regards,
Bins.

Hello guys, come on, please suggest...

You can buy a switch all ready to take the resistors from Goldpoint, no guesswork required...

it would be good "idea" to take in account input impedance of the input stage of the amp

Bump up...

Hello,

Guys, My only problem is in identifying the terminal with the rotary switch I am having. All the resistors are ready to go...

Does anyone have tried a similar one?

Best regards,
Bins.
