4 pole 5 position ceramic rotary switch
The switches have been manufactured in Russia for military. Rotary Switches turning with really old "electric-ceramic" boards. Designed for use in high-and low-frequency AC and DC currents in electronic equipment. PGK are manufactured for all temperate and cold climates. All contacts are evenly distributed in a circle at 30 degrees.
There is a mechanical limiter (a pin) that could easily convert this switch (example, from 11 throw to any throws you like - from 2 to 11 throw switch, or from 5 throw to any throws you like - from 2 to 5 throw switch). This is a high quality ceramic rotary switch with silver plated contacts/soldering terminals. Very low contact resistance.
