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

  • How can I connect this to a 6 outlet power supply? I am a noob at electronics.

  • Do less "clicky" variations of this switch exist?

  • I'd buy one of these if it had a level and was rated 5A, like this: http://www.radioshack.com/product/index.jsp?productId=2049718&znt_campaign=Category_CMS&znt_source=CAT&znt_medium=RSCOM&znt_content=CT2032230#

  • The current rating for this switch says 4A in the description, but 3A on the switch itself. Not a big deal because I won't even get close to that, but watch out!

  • Is there a datasheet available for this switch? I'd like to know what the operating force for this and the 2-terminal switch is.

  • It's a shame this one doesn't come with a lever, or the one with a lever only has 2 terminals. I really need a NC microswitch. Tempted to hack the 2 terminal...
