I want to label a spare electrical switch "spare" in Spanish

Question

I want to label a spare electrical switch "spare." What Spanish word comes to mind for this purpose???

Answer 1

Cambio eléctrico de repuesto

You could also use adicional, de más or auxiliar in some cases.

I hope this helps.

• I need one word as I have limited space would "auxiliar" be appropriate? - xavier969 Sep 23, 2009
• Repuesto would be the best word. - Nathaniel Sep 23, 2009

Answer 2

Is this "spare" as in "unused", like if I had a circuit breaker in a panel to which nothing was connected or "spare" as in redundant or extra? If the motor control center doesn't automatically start the motor, we have a spare, manual, push-button, starter switch for engaging it.

repuesto o sobrante if you only have room for one word.

auxiliar if it's redundant.

• In common USA electrical useage, a breaker marked "Spare" is one with nothing connected to it. - Goyo Sep 23, 2009
