Selector switch

[gimpchop]

Hi I'm trying to add a selector switch to control inputs i.e tape CD mp3 ECT but I don't know what type of switch to order. I know I want a rotory style switch but as for how many poles I need. Thanks

Hi, poles are separate switches, ie, stereo you'll need 2 pole, then ways is the number of sources you want to switch

You need an X position 2 deck rotary switch for stereo, where X is the number of different sources.
Tape, CD, and mp3 would be 3 sources, so that's a 3 position 2 deck rotary switch.
Each deck is for one channel. Some switches however can have both channels on the same, single deck.
Of course you can get a switch with more positions than you need, and ground the extras.

This one perhaps ? It Switches Stereo since it has 3 poles.
Third pole You can use to switch source Led indicators.

You'll need a two-pole switch with as many positions as you have sources. Note that some switches, like the Lorlin (EU) or C&K (North America) switches have stops that are movable. In those cases you can buy a two-pole, four position (or four throw; 2P4T) switch and move the stop one position and get a 2P3T switch out of it.

Ideally, the switch should be break-before-make, i.e. it breaks the connection with source #N before making the connection with source N+1 when you rotate the switch. Most switches are break-before-make.

Try these:

Free delivery on orders over £5. Just type Lorlin into the search box and you will see all the options. A 3 pole 4 way would also allow you to add an LED indicator to show which source was selected.

I like using a four pole for stereo. Parallel two poles for each channel. Less chance of a dirty contact. Plus less noise in theory.

I like a single pole switch energizing a two (or more) pole relay.
