Title: Electrical switch assembly comprising a piezoelectric sensor disposed between parallel mounting plates
Inventor: KRAJEWSKI JAMES R
IPC: H03K17/96
Filed: 2019-08-07
Abstract: The present inventors have recognized that an electrical switch for opening doors in buildings, calling elevators, and the like can be improved to require less physical contact, larger activation area, and multiple activation methods, with increased reliability, by utilizing a piezoelectric sensor specifically arranged between rigid, parallel mounting plates in which one of the plates (an inner plate) is rigidly fixed to prevent movement while the other plate (an outer plate) is accessible for receiving physical contact. By rigidly fixing the inner plate, such as by mounting to a wall or bollard, the sensor can react with sensitivity upon an application of less pressure on the outer plate. Such pressure compresses the sensor between the plates to produce an electrical signal. A controller receiving the signal can, in turn, execute to open a door, call an elevator and/or activate a light or sound to provide feedback.
