Swiss Micros and WP34s...

I was referring to the new SwissMicros DM 15L. The Enter key on all of these calculators, HP-15c, HP-15c LE and DM 15L will operate when depressed at the top or middle, but only the DM 15L will not operate when depressed at the bottom, because the key will not move. I believe that all these calculators have two switches assigned to the Enter key.

Edit, I just got the Enter key to work on the DM 15L when depressed at the bottom. It seems that I just needed to give it a really hard initial push to break it free, and it's now working normally. It does require significantly more effort to press at the bottom than at the top, which is similar to the other ones. So, I guess you can now disregard all that I said previously.

I looked inside of my DM-15L and the Enter key is designed to depress only at the top. All of the keys on the DM-15L have a thin-plastic flex hinge at the bottom and a nub near the top that depresses a snap dome underneath. The Enter key is no different. Even though there are two snap domes under the Enter key, only the top one is used. The hinge at the bottom of the Enter key isn't supposed to depress. It only moves at the top. If you follow the advice above, you will BREAK the hinges off of your Enter key and it may not work as consistently or reliably thereafter (The Enter key might possibly even fall out of your calculator once the hinges are broken off). After one understands how the key is constructed, it's relatively easy to remember to press the Enter key at the top.

Hope this helps, Barry
