Deleted. I see you're looking specifically for a switch with a 10mm thread...

While I previously said 87 was not used, I should have mentioned the option of using post 87 for a low oil pressure warning light. The 87A in this case works as the NO line, 87 will be the opposite, it will be NC, hence when oil pressure is lost, this leg will close and energize the warning light. You can buy 1/2" very bright to install in your panel in a variety of placed.

Here are the ones I like and use...

Default Version 2 with oil pressure warning light

I decided to update the drawing. I added the master contactor that RV7 Charlie mentioned. I also added the low oil pressure light leg off post/terminal 87 on the relay.

When using warning lights, it is also good to add a "push to test" button so you can push it to ensure the lights themselves are functional as a preflight duty.
