Additional switches – which are available and what are the part numbers?

Hello everyone, I want to install additional lighting and have a switch suitable for the vehicle. I have a blind switch in my switch block next to ZV and rear window heating. Such a switch block is needed – but only in the whole. Also that wouldn’t be bad – I could just remove and convert the switch there. But sometimes the tendency to perfectionism also swings: 1. I find this stupid, if on a S I don’t know how these switches work and are switched on – they are buttons, they have a double occupancy…. I need a very banal toggle switch for on/off, which I can fit into the blind socket. Maybe there are also different symbols. But also without me. Bonus would be a light-emitting diode in, but doesn’t have to be. If someone knows something like that, you know, where i am. And if there is, how are the part numbers? Thank you for the support!
