Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

Customer Comments

  • A three pack for use with 3D printer builds would be nice. (Though buying two two packs and having a spare isn’t bad at this price.)

    • You would need six for a 3d printer.

      • Most printers only have endstops at one end of each axis. They’re for calibration at startup, not to protect the printer from going to far like in a CNC Mill, because the stepper motors in a printer rarely have enough power to damage anything.

  • For the record, this switch is an MX11-3D from JL Electronics (aka Zhejiang Jialong Electron Co., LTD).

    For a dimension drawing, go here and click on the picture of the MX11-3D switch – or any of the other similar switches – and you’ll get a popup with your measurements and all. There’s a button on the popup, amusingly labeled “View the Switch Diagram”, which takes you to a specifications table.

    This switch is rated 2a @ 24vDC in addition to being labeled for 3a @ 250vAC. (Not 5a @ 250vAC as our benevolent overlords would have us believe… ;) :P )

    I hope I’ve been helpful to someone :)

  • What would the pinout for this be? I’m having trouble locating the datasheet. Thanks!
