short circuit
A faulty, direct connection between two poles of an electrical voltage source that leads to a very high current flow and often causes damage or fires.

rash impulse
In a figurative sense, a thoughtless, hasty, and often wrong action or way of thinking in reaction to a situation. Often used as 'Kurzschlussreaktion' (knee-jerk reaction).
Seine Kündigung war ein Kurzschluss, den er später bereut hat.
His resignation was a rash impulse that he later regretted.
The word consists of 'kurz' (short) and 'Schluss' (end/connection). In electrical engineering, it describes how the current takes an unwanted, 'short' path instead of flowing through the device.
Ein alter Toaster hat den Kurzschluss in der Küche verursacht.
An old toaster caused the short circuit in the kitchen.
You can recognize the technical meaning from words like 'Kabel' (cable), 'Sicherung' (fuse), or 'Gerät' (device). The figurative meaning refers to human behavior and is often combined with words like 'Reaktion' (reaction), 'handeln' (to act), or 'Entscheidung' (decision).
Wegen eines Kurzschlusses fiel der Strom im ganzen Haus aus.
Because of a short circuit, the power went out in the whole house.
In a technical context, 'Kurzschluss' (short circuit) is often used with certain verbs: it is 'verursacht' (caused) or 'ausgelöst' (triggered), or you 'hat' (have) a short circuit.
Das Wasser in der Steckdose hat einen Kurzschluss ausgelöst.
The water in the socket triggered a short circuit.
In the figurative sense, the word is very often used in the fixed combination 'die Kurzschlussreaktion' (knee-jerk reaction). The expression 'im Kurzschluss handeln' (to act on a rash impulse) is also common.
Er hat im Kurzschluss gekündigt und es am nächsten Tag bereut.
He resigned on a rash impulse and regretted it the next day.
