today i was thinking of buying switches to play around with to see what i like. But i couldn't decide which switch to get. I was eyeing a switch grab bag on jameco for $24 usd. All i have now are the basic breadboard momentary tactile switches that are okay, but aren't really exciting. I've also been looking at rotary switches and analog joysticks to mess around with.

For immediate playability within the Lunetta world (extending to the modular synthesizer world), I'm happy with your most basic SPST (single pole; single throw) switches. 2 connectors. Allowing you to have something pass through the switch, or not. Depending on whether it's turned on or off.
As well, you can get 'momentary' versions of this switch, which will act the same way as the push button switches that you had on the bread board. (Which are also SPST.)

Rotary switches, can allow you to switch 1 pole (1 thing) between 3 to 24 different destinations. (Possibly more. 3 to 12 being the most common.) They are great for multiple choice situations.

So a 24 pack? If the pricing is decent, there could be some interesting ones to play with.

Don't forget that transistors (and even diodes) can be used as switches.

A bipolar junction transistor is a current controlled switch.

A CMOS transistor is a voltage controlled switch.

Oh, right. And don't forget the analog switches 4066 and multiplexers 4051, 4052, 4053. Great to introduce variations in a circuit, and can be controlled by other outputs as well as simple mechanical switches. Less exciting haptic experience than a rotary switch, however.

Don't forget the CD4007 which can do all kinds of crazy stuff. I call it a CMOS transistor array Cool

It's a 150 piece pack for $24 usd on jameco electronics

Doh! My pardon. I have to learn how to read. Haha.

That's a nice price for experimenting! 6 switches for $1 (before shipping costs)? Even if all of the switches are "off shore" quality, that will still give you a fair # of options to play with for experimenting! Smile

So, since then. I've gotten a few new ICs, rotary switches, buttons, toggle switches. Also i finally found some joystick potentiometers, not to be confused with analog sticks.
