I am currently working on a Digital multimeter design and I am looking for a connector to select appropriate voltage rating, as well as resistance measurement and other multimeter functions. I need a rotary 12 position 2 pole connector to achieve these ends. I found the PLR series which only handles voltages of 250 AC and .15 A. Now I could bypass this for the current measurements but I really can't for voltages exceeding 250 V and I really don't want do it for the current draw selection. How do multimeter designers deal with the high voltage coming in on the rotary switches. Is there a switch out there that can handle greater voltage and currents?
