An electric or electronic animal trap with a CPU-controlled, rearming, multiple killing plate (18,22,24) configuration and automatically resetting mechanical switch (32) for triggering a high voltage cycle. A high-voltage output circuit (10) is connected to killing plates which are activated with a high-voltage pulse train when a pest closes the mechanical switch (32). The trap is configured to automatically rearm an indefinite number of times until a first dispatch is detected. Once the first dispatch is detected, the circuit will automatically rearm twice more. Accordingly, a plurality of mice may be dispatched and retained within the trap before the trap requires servicing.
