Title:
PRESSURE SWITCH
Document Type and Number:
WIPO Patent Application WO/2023/238520
Kind Code:
A1
Abstract:
Provided is a high-quality pressure switch. The present invention comprises: a base substrate 2; a lid substrate 3 that, by being bonded to the base substrate 2, forms an airtight space between the lid substrate 3 and the base substrate 2; a deformable diaphragm 5 that is formed at a position corresponding to the airtight-space of the lid substrate 3; a lid-side movable contact electrode 8 that is disposed on the diaphragm 5 and serves as a movable contact; and a base-side fixed contact electrode 11 that faces the lid-side movable contact electrode 8 with a prescribed gap therebetween and serves as a fixed contact. An electrical connection is toggled by the lid-side movable contact electrode 8 and the base-side fixed contact electrode 11 coming into contact or separating due to deformation of the diaphragm 5. The base substrate 2, the lid substrate, and the diaphragm 5 are each formed from quartz or glass.
