Is there a simple short circuit protection available?

One of my little copy/paste projects died again (a 12V 1 A circuit - last time it died). Now it was a short that caused it.

Is there a simple way of keeping my parts from burning? By simple I mean something like a resistor that will burn before more expensive parts will, and that will cause the circuit to stop receiving power.

Also what are the problems that come with being simplistic?

Edit 1: So the circuit after all the answers looks like this:

• $30\:\text{V}$ (AC and/or DC) seems excessive for a $12\;\text{V}$ relay. Is this the actual situation you need to cope with?

• Is there a simple way of keeping my parts from burning? Sure! Operate them within their rated parameters! If what jonk says is true and you do operate a 12 V rated relay at 30 V then for sure you're asking for trouble. Nov 1, 2019 at 7:02
• @Bimpelrekkie Since that time I have found a 15V AC/DC and after all the circuit it gives less. Nov 1, 2019 at 7:40
• Hmm, so the actual circuit you're using isn't shown in the linked question either. Then your question is similar to: I build something, but I'm not showing you what it is, it has a problem, how do I solve it? What makes you think that we do not need a schematic of what you made?

• Because the linked circuit shows a 30V supply but your said you use 15V. Nov 2, 2019 at 11:47
