Think is this model:https://www.rapidonline.com/rvfm-solder-tag-rotary-switches-30304
They dont call then MON-OFF or ON-OFF, but: "Available in make before break or break before make versions"
Thanks Sokol , that is good info that link is to ALPHA (Taiwan) brand switches , which is the same brand I got the other day so if I am lucky they will have those plastic M-b-B or B-b-M Switches too.
- I will need a Break before Make (B-b-M) correct? so it is off normally,and on when "switched"
some more info in case there are others like me ............
Break-Before-Make
Definition
Break-Before-Make: A switch that is configured to break (open) the first set of contacts before engaging (closing) the new contacts. This prevents the momentary connection of the old and new signal paths.
Applies to mechanical systems (e.g. that use relays or manual switches) and to solid-state analog multiplexers and switches.

Make-Before-Break
Definition
Make-before-break: In a switching device, a configuration in which the new connection path is established before the previous contacts are opened. This prevents the switched path from ever seeing an open circuit.
Applies to mechanical systems (e.g. that use relays or manual switches) and to solid-state analog multiplexers and switches.
