Taiss 3pcs Rotary Switch RS26 2P12T Band Switch Band Channel Rotary Selector Switch 2 Pole 12 Position Selectable Position + 3pcs knob

These are small enough to fit is a tight space. I was especially looking for a nine position rotary and the drop in clip allows this switch to be configured as a 2 to 12 position single pole. To set the limit clip, first rotate full CCW, then select the desired number of positions, drop the tab on the clip into the marked slot (number is on the left of the slot) and add the lockwasher and nut. If you do not rotate full CCW first you can get trapped on the CW side of the limit clip.

I think these are all 4 pole 12 position switches but they include a stop to limit the number of positions. For the money these are awesome switches, including the knobs!

These are Pcb mount devices. However they are very sensitive to the amount of pressure exerted when forcing them into the Pcb. I have made my own Pcbs with autodesk eagle software, but the mounting holes need to be slightly larger than 1mm. If the switches are forced into smaller holes the internal pads are misaligned and can create contact problems. Otherwise, the switches behave as designed when the stop washers are installed properly when the switch is turned all the way CCW

The switch index can e set by inserting a washer that is keyed. This will limit the rotation so if you only need a 2 or 3 position switch it is easy to “lock out” the positions you don’t need.This is typical of these types of switch constructions. Worked for me!

This is a 12-position rotary switch that turns in a full circle -- 30 degrees per position. I used it to provide power to one track at a time around a model railroad turntable. If you don't need a full circle with 12 positions, it comes with a limiting washer that can stop the arc at 2-11 positions. Easy to mount on a 1/8" panel with included nut & lock washer. Pins for the power wire and the output poles accept standard Dupont pins so you don't need to solder the connections and can vary the poles you connect to easily.

The body should be made of metal. It’s very hard to securely mount these without them rotating in the hole because the body is plastic and you can’t torque them down very much without stripping the threads.

I was looking everywhere to find different types of rotary switches that I needed for a project, finally found these that are amazing! you can configure them the way you need. Really a bright idea in this design.Well designed, well constructed and at reasonable price.Highly recommended.

Appears to work pretty good, but the knob is really hard to rotate, and the odd placement of the pins makes them very difficult to use unless you have a custom PCB board, or an application that specifically requires this as a replacement part.
