Electric Rat Trap
Rat-Trap Model #1
This was the first device which its frame was made by wood and had low efficient motor gears to trap rats. Also it had many electric connectors which its wires were not well organized in one circuit. Besides it was big in dimensions of 29cm x 23cm x 21cm.
Rat-Trap Model #2
This was the second device which its frame was made by metal (galvanized) and had low efficient motor gears to trap rats. But it had improved electric connectors compacted as one which its wires were well organised in one circuit. However it was still big with same dimensions as previous model, of 29cm x 23cm x 21cm. It has a sliding switch for trapping and reset.
Rat-Trap Model #3
This is the third device which its frame is made by metal (galvanized) and has high efficient motor gears to trap rats at fast and reliable speed. It has been improved electric connectors compacted as one which its wires are well organised in one Printed Circuit Board (PCB). It is made small (3/4 reduced size) with dimensions of 22cm x 13.5cm x 12cm. Trapping and Reset switch is improved to Toggle switch.
