# Help identifiying button type

I'm building an LED lamp and I want it to have no ON/OFF switches/buttons sticking out from the lamp. The switch function I would like to have is like a pushbutton: You push it and it pops out and then you can turn it as a potentiometer and then push it back in.

I have seen the kind of switch I'm describing, but I don't know how it's called. One example where this kind of swich is used is in Opel Astra radio panel.

Any ideas how is this switch/button called?

it is a latching push button switch
