Micro breaker for portable device and method of manufacturing micro breaker for portable device

摘要

Prevent momentary interruption due to strong impact. Without high accuracy required for parts processing and assembly, instantaneous interruption is reliably prevented while mass-producing at low cost. The microbreaker is a microbreaker for a portable device connected in series with a battery, and includes a movable contact plate (1) having a movable contact (3) provided at the tip of an elastic arm (5), and a movable contact (3 A fixed contact plate (2) provided with a fixed contact (4) at a position opposite to the fixed contact (4), and a bimetal (6) that turns the movable contact (3) off the fixed contact (4) at a set temperature, A PTC (7Y) for preventing instantaneous disconnection is provided which is connected to the fixed contact plate (2) and the movable contact plate (1).
