- 2 momentary pushbutton switches 1 rotary switch with 6 positions D 4 rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one side //calculated x value of exact middle of panel after deducting left/right sub-panels // top horizontal rib // middle horizontal rib // one more vertical to mount the circuit board sideways on HP = 5.075; // 5.07 for a 1uF capacitor; expand a bit, but also size it for a single 2 mm² wires, reinforced.
