What you have to say about this?Well you are using P channel Mosfet that will not work as I can see. Use NPN BD 139 Transister.

what is the issue than ? yo uonly need to choose the right component rating, your circuit work perfectlyI have done this a few times and the end solution never looks elegant.
I need to switch (control) a 500ma, +12V source ( with 5V logic). The switch must Source not sink.
Please show me your elegant solutions.
Here is a 4 component $0.40 solution

No voltage at the load!

Here is a 1 part SOT-363 165 mOhm $0.09 High Side 1A switch with extra parts for slew rate control. +/- 1.1A

Electro-Static-Discharge = ESD . This part has protection with intrinsic diodes.

This is a half bridge (complementary) emitter follower. THis is equivalent to SPDT between V+ and gnd but with Vce-saturation voltage drops and use where low impedance is but voltage drop is not as important.
