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.

A magnetic type keyswitch includes an actuating member and a switch unit. The actuating member is movable in response to a pressing force. The switch unit includes a circuit board, a Hall sensor electrically connected to the circuit board, and a magnet spaced apart from the Hall sensor by a fixed distance. When the pressing force is not applied, the magnet enables the Hall sensor to output a first voltage, and when the pressing force is applied, the actuating member moves relative to the magnet and the Hall sensor in response to the pressing force, so that the Hall sensor outputs a second voltage different from the first voltage, and the magnetic type keyswitch generates a triggering signal.
