Description: Simple SPDT slide switch. Rated at 30V/200mA. The pins have .1" spacing - fits great into a breadboard! Use it as a power switch or general control switch.

  • ahh, sparkfun. you’re all breadboard and pcb friendly, yes, but when will you realize that you need through mount-screw in and screw-on (like with a screw over the whole switch/potentiometer) spdt switches, rotary encoders, and potentiometers… in practical applications most of these interface devices need to be mounted flush with the face of an often-used surface (not a breadboard) and hot glue doesn’t cut it holding those in those cases. you need hardware mounting solutions… sad but the local radio shack is beating you on this field. please get some in!

  • I am pretty sure this is the Datasheet: Part: EG 1218

    • Its funny I searched for hours for the right sized switch and eventually found this one at mouser, then just found it here. This is literally the only size that will fit in my project, which runs 5v @ 2-3A (Spiky from led-strips). lol Ill make sure to tell you how it goes, but I did find an old tiny switch just like this that couldn’t of had a higher rating and it worked fine. Absolutely no problems. Though this wouldn’t work for a constant high amperage

  • Your eagle library has this part (com-00102) put it’s definitely not this switch!

  • (Redundant post - also at #9609)
    Could this be used with 9v at ~600 mA? I’m building a personal fan prototype with my mini breadboard (stuck to a foam block from the maglev train kit me and my friend used for NY SciOly xD) and I need either this or the other one here…

    • Should be fine. As long as your overall power remains the same (9 x 0.6 < 30 x .2)

      • Um, no. This is not a resistor which is dropping 9V or 30V, it’s a switch which must be able to block 30V of DC when off (which is tiny BTW), not destructively arc when used as an interrupt, and not melt due to power dissipation when on.

        With specs this tiny on a physical switch, you might never see a failure operating at 9V/600mA, but, as a general rule with switches, the voltage rating is independent of the current rating.

      • Thanks!

  • Can you get a switch with higher amp load. Like some stepper drivers can go 38V 4amps per phase.

  • It appears to be an MMS1208 from APEM

  • Are these “stackable”, i.e. you can put a number them next to each other on a 0.1 inch grid?

  • Datasheet for this part? Or reference number to search it?
