Default Help with rotary switch type

Searching for a 2-position, single pole non-latching (returns to mid position) rotary switch. Any suggestions?

Hi,
make one. remove the solenoid of a relay and use a lever attached to the knob shaft to actuate the contact mechanism. The shaft can be as long as you require to suit the best location of the switch.

Making one (although not from a relay) was my first thought.

Cannot figure out a simple way to get the shaft back to neutral central position.

This is what i want to emulate.

By "two position", do you mean that the center position does nothing, and there are left and right momentary positions?

And how much mechanical travel should it have?

Is it for something like an incrementing/digital volume control?

There are toggle switches that have momentary positions, like that, e.g. (on)-none-(on) or (on)-off-(on). The parenthese are usually used to denote a 'momentary' position. Maybe your 'switch' shaft could actuate one or more of those types of switches, using something attached perpendicular to the shaft (perhaps a small open cylinder, which could fit loosely over the toggle switch's handle).

Or, you could run a rod through your rotary shaft (or otherwise attach a perpendicular piece of some sort), and have each end of it able to depress a momentary pushbutton switch.

Both of those would require the shaft to have some other rotary type of mounting, probably at each end, i.e. bearing or bushing or whatever, and something to hold it all in place.

Otherwise, you might need to attach a couple of springs, somewhere, on an otherwise-suitable rotary switch.

Hi Gootee

Thanks for the reply.

It is exactly what i'm looking for and i'd rather buy a factory made switch (surely Audio Research are not making these in-house) than mess around and end up with something that will not have the correct tactile feel.

Bearings, bushings and springs are not my idea of diying

Take a look at Allen Bradley, they have several of those switches at reasonable cost.

This series has just about any option you'd ever ask for.

The 800A series are 16mm, maybe is better for you application, but I think is harder to find.
