Title:
PAN DETECTION SWITCH
Document Type and Number:
WIPO Patent Application WO/2019/031213
Kind Code:
A1
Abstract:
Provided is a pan detection switch having a structure with which the influence of disturbance, such as heat, can be suppressed, and which can be implemented at low cost and in small size. The pan detection switch comprises a configuration in which a reed switch (1) advances into or retreats out of a magnetic case (2) due to application of a pressure to a pressure receiving portion (3). The pan detection switch is characterized in that: the reed switch (1) is provided with, at fixed positions, a magnet (9) for forming a magnetic field and a contact (10) that closes in an effective magnetic field of the magnet (9); and that the magnetic case (2) replaces the contact (10) into and out of the effective magnetic field of the magnet as the reed switch (1) advances or retreats.
