Switch Question

Postby BrightonMan » Sun Jan 19, 2020 7:55 am

I recently acquired a few of these switches. I believe they are DPDT? The switches themselves have an on/off movement but on the side it says on/on. There are six terminals on the back. My question is, can these be used as simple on/off switches (for isolating sections etc) or are they for something more complex?

DPDT means they are double pole double throw.

They can be used as on-off switches by connecting between the centre terminal and one of the matching end terminals. As they are double pole they can switch 2 independent circuits at the same time if required.

There are two types of DPDT switches, single throw (top to bottom) and "centre off". Normally where they put "on" and "on" they are centre off. Not that it makes any difference to your question but can you move the toggle so it stops in the vertical position?

No, either top or bottom but not the centre.

The OP says that the switch is marked on/on, one with centre off would be marked on/off/on
