Encountered some bad UX the other day

You press down to get it up

Sometimes everyday-life riddles you. What am I talking about?

(Probably not bad UX but I remember the first time I encountered it and I remember being a bit confused (I was quite young), my brain is used to the convention now)

• Judging from the answers, this question is a little 'broad'. Could you give something more to narrow it down a little? – PL457 Mar 23 '18 at 11:31
• 'Correct' answer has already been given, but cannot accept within 10 min. I agree it's broad, It'll drop away soon. I leave it as is. I actually tried some to make it a proper riddle, but they all came out boring and convoluted :) – Adam Mar 23 '18 at 11:34

Is it

An elevator button?

Because

You press the down button to call the elevator up (if it is currently below you).

• Comment on riddle being to broad: Hmm I maybe should've had the same riddle but the question to go along with it could've been 'Where are you?' --> top floor – Adam Mar 23 '18 at 11:37

Is it

pressing on the weighing scale?

as

you push down(apply more pressure) and it will go up(weight)

It can also be,

bread in toaster (or may be I am just hungry)

Is it

a Pedal bin?

because

You press the pedal down and the bin lid goes up.

Why the UX (user experience) fits in.

You don't have to get your hands dirty to dispose of your trash.

• it can also be pedal on bicycle (only one pedal)? so other one goes up – smriti Mar 23 '18 at 11:29
• Bicycle pedals aren't that confusing for little children, are they? – PL457 Mar 23 '18 at 11:33
• I guess you are right, but as a child, i was amazed, after seeing them work first time – smriti Mar 23 '18 at 11:40

I know there's already an accepted answer, but this fits quite well too:

A website with a scrollbar.

Because..

If you press down on your keyboard, the contents of the website itself move up.

Is it

A trampoline (or any spring-device like a Pogo stick)

Because

In order to go up, you need to put pressure down
