Abstract:
An over-current protection device includes a first conductive member, a second conductive member, a resistive device and a temperature sensing switch. The first conductive member includes a first electrode foil and a second electrode foil those are formed on a same plane. The resistive device is laminated between the first conductive member and the second conductive member and exhibits positive temperature coefficient or negative temperature coefficient behavior. The temperature sensing switch can switch the first electrode foil and the second electrode foil between electrically conductive status and current-restriction status, e.g., open circuit, according to temperature variation. The threshold temperature of the temperature sensing switch is lower than the trip temperature of the resistive device.
