Basic question: How much to tighten crush washer?

I am going to swap out the oil pressure sensor on my 1991 300CE. It attaches with a copper crush washer. How much do you tighten this? Is it similar to an oil filter, finger tight then 3/4 more turn? Or like a sparkplug and washer? Just tighten until you feel it crush?
