This is an SPDT micro switch

It appears to be a microswitch, of the momentary on (momentary on on one side, normally open on the other) type with a roller arm on it.

This type of switch, with or without the roller, is often referred to as a micro switch...

Three pole micro switch with (and hear the maker calls the roller whatever they want)

Yes. i think that your comments is true but If you are using a switch without the roller,"lever arm switch" would be correct. Here's a Web page from a company which sells them: "


Visit us and test drive a new or used Butte MT Trucks, Montana Chrysler Dealership, Butte MT Used Cars, Used Cars in Montana, Montana Car Dealership, Montana Dodge Dealership, Montana Jeep Dealership, Montana RAM Dealership, Butte MT Car Dealership, Butte Car Dealer. Our Montana Chrysler Dealership always has a wide selection and low prices. We've served hundreds of customers from Deer Lodge, Anaconda and Whitehall.

In switzerland we also use the english word for them: Micro-switch.
Stupidly, if it is the big brother (in geometrical termes) of the micro-switch, we simple call them "Grosser mikro-schalter" --> "Big micro-switch". Stupid but true :)

Kelseymh and gmoon, thank you for your comment.

You're most likely to find it using the full name, roller lever arm switch, though it may also be abbrevated to just "roller switch."

Roller switches are commonly used as limit switches (e.g., for opening or closing a door or gate). They are typically momentary-contact switches, and may be wired as either normally open or normally closed (hence the three pins you see) depending on the application.

You should be able to get it at any electronics shop (even RadioShack, way in the back behind the cell phones) or even a hardware store with a decent electrical supplies section.

Thank you very much for the response. I only needed the name for my instructable. What is the name without the roller just "lever arm switch"? Thanks again! Mischka

Yes. If you are using a switch without the roller, "lever arm switch" would be correct. Here's a Web page from a company which sells them: http://daltonengineering.co.uk/electrical/lever-arm-switch-for-cyclone-control-pan-and-power-winch-limit-switch.html
