Het is dus een draaischakelaar.Heel kort de werking van die schakelaar:

Hij schakelt dus 7/5/12.There are four groups which I arranged by colors. When the switch is in Position 1, all the "1's" are active with their respective letter pole - a1, b1, c1, d1. When the switch is in Position 2, all the "2's" are active with their respective letter - a2, b2, c2, d2. And when the switch is in position 3, all the "3's" are active - a3, b3, c3, d3... Thus, the switch has three positions.
