    Hi all! First post, so take it easy on me!

    I bought a metal detector pinpointer from Harbor Freight (which I knew was going to be a bit dicey) and on the first day out of the gate the button started to fail, so I want to replace it with a better button. ( I can't just return it because I've had it for a while, just not used it.)

    The button is a square, non-toggling one, and by that I mean it doesn't click and stay on, then click and stay off. You need to hold it in to keep it on.

    I opened the pinpointer up and checked the wires that the button are connected to, and they seem to be on there fine, and the button is encapsulated, so I can't dig into it any further.

    I'd like to buy a new button online, but I don't know what to call the darn thing when I'm looking it up. I went on one electronics retailer and they had over 9k buttons alone!

    Here is a link to the pinpointer on their website and the button should be pretty clear in the picture. http://www.harborfreight.com/metal-detector-97245.html

    Any help on what kind of button I should look for would be greatly appreciated!

    Thanks!

    sounds like a common ' momentary' type.
    you need a momentary switch that is closed when pressed.

    If it doesn't work take it back to Harbor Freight for an exchange.

    Google it. "Momentary switch square". Here's an example:

    http://www.digikey.com/product-detail/en/B3AL-1000P/SW1216DKR-ND/2698555

    You can get more specific results, the more info you supply. The voltage rating, the size, the contacts (SPST/SPDT? how many wires are going into the switch), mounting type, etc...

    Digikey and Mouser have good search engines.

    Thanks a lot everyone! The switch only has 2 wires going into it, soldered on a pretty simple connector I think. The kind with the tab with a hole in it. Now to buy me a switch and some helping hands! Should Digikey and Mouser be fine shipping to Canada?

    I suppose I should measure the foolish thing as well, eh? KMoffett, normally I'd bring it back for sure, but the nearest HF is about 6 hours away, and the pinpointer was only $9, so I'm going to try to fix it. I bought it last fall and just stored it for the winter.

    My preference is Digikey, they ship for a flat rate of CAN$8.00 to Canada, no duty or brokerage, just PST/HST.
    It is on my doorstep by 12:00 next day air.
    Over $200.00 no postage.

    If you live in Ontario you can visit a Sayal store and select the pushbutton off the rack. There are seven stores across Ontario.

    I'm in NB and the only place I could think of is Radio Shack 20 years ago, heh.
