I'm going to install Micro switches on my machine are this the right ones

Hi James

Microswitches bounce when they close, not when they open.

If you want to avoid bounce, without extra circuitry, set your position when the switch opens.

Do you "do" electronics?

If you want maintenence free precision consider an opto-slot with Schmitt trigger.

If you want zero hysteresis consider a standard, photo-transistor opto-slot and feed it into an op-amp wired as a comparator.
