In Part 3 of this 4 part series, we look at Frog polarity and microswitches within the PL-10 system. This involved the PL-13 Accessory Switch, the PL-15 Twin Microswitch, the PL-19 Microswitch Housing, the PL-32 Microswitch Open Type and finally the PL-33 Microswitch enclosed type.
We will also explain what a 'Frog' is and what it does.
This will include PECO 'Insulfrog' and how it works, 'Electrofrog' and what this does for polarity switching, and also the newly developed 'Unifrog' and the benefits of this.
We will also cover how to fit these switches and how they work.
