Indesit kd3c11 6 position switch

Indestit freestanding cooker – kd3c11(x)g
Looking for the part no for the rear left ring control.
The hob controls are all 6 position switches, 1 is an ego type switch, the other 3 are I think called Dreef switches.
The switch I’am looking for is the dreef switch.
Connect only show the ego switch.

Are they interchangable?

Noticed that the switches operate anticlockwise, position 1 at 10 o clock,
Is this common for 6 position switches ?

Any help much appreciated.
