How does a rat trap work? - briefly
A rat trap employs a spring‑loaded bar linked to a baited trigger; when the rodent pulls the trigger, the spring releases, snapping the bar shut and immobilizing the animal instantly. This rapid closure prevents escape and kills the pest with minimal struggle.
How does a rat trap work? - in detail
A rodent trap relies on a spring‑loaded lever that stores potential energy. When the trigger is disturbed, the lever releases, converting stored energy into kinetic motion that drives a bar or platform forward at high speed. The forward motion closes a cage, snaps a jaw, or propels a weighted bar onto the animal, causing immediate incapacitation.
The mechanism consists of several key components:
- Trigger assembly – a sensitive plate or lever connected to a small bait holder. Minimal pressure from a rat’s weight or a touch releases the latch.
- Spring or coiled steel – compressed during set‑up, it provides the force needed for rapid movement.
- Striking element – a metal bar, snap‑jaw, or drop‑door that contacts the target once the spring expands.
- Containment chamber – a cage or solid base that prevents escape after activation.
Operation proceeds in three phases:
- Arming – the user compresses the spring, engages the latch, and positions bait on the trigger.
- Sensing – the rat approaches, applies pressure to the trigger, or nudges the bait.
- Activation – the latch releases, the spring expands, and the striking element moves within milliseconds, delivering a force sufficient to kill or immobilize the animal.
Design variations adjust the speed, force, and safety features. Snap traps use a hinged jaw that snaps shut, while live‑catch traps employ a drop door that seals the animal inside. All rely on the same principle: a pre‑loaded energy source released by a minimal stimulus to produce a rapid, lethal or restraining action.
