Update on 3rd February 2023: Royal Mail are still requesting people to stop posting new orders internationally through the Post Office. This is to allow them time to rectify the problems they are still having after the cyber attack a few weeks ago. Any international orders placed will be held until we are able to post them again.
We apologise for any inconvenience this may cause.
As the name denotes, rotary switches are activated by rotating a knob. They are generally needed when the number of circuits that need to be changed simultaneously exceeds the capacity of a toggle or slide switch. Rotary (Multi-way) Switches have many conducting positions. They may have several poles (contact sets). They are available with a range of contact arrangements from 1-pole 12-way to 4-pole 3-way. For different variants of the rotary switch, the number of "ways" (switch positions) are reduced with a different "stop" under the fixing nut, limiting the movement where there are more poles to be served.
