A keyswitch device which is provided with a support mechanism which supports a keytop in a movable manner, and a membrane sheet which has a plurality of upper electrodes and a plurality of lower electrodes which respectively correspond to the plurality of the upper electrodes and which form contact pairs with the corresponding upper electrodes. A plurality of contact pairs are arranged for a single keytop. The rubber cup pushes the plurality of contact pairs which are arranged for the single keytop.

A membrane digital analog switch includes an input button surface adapted to receive an input pressure from a user, and a digital switch positioned below the input button surface to generate a digital switch activation signal when the received pressure on the input button surface is greater than or equal to a specified digital pressure threshold. The membrane digital analog switch also includes an analog switch adapted to generate an analog switch activation signal when the received pressure on the input button surface is greater than or equal to a specified analog pressure threshold. The specified analog pressure threshold is greater than the specified digital pressure threshold, the digital switch activation signal is a binary digital signal, and the analog switch activation signal is variable and corresponds to an analog sensed value of the received pressure on the input button surface.

To provide a seat occupancy sensor capable of detecting that an occupant is seated on a seat, a seat occupancy sensor (10) provided in a vehicle seat (1) includes a pair of switch modules (16, 17, 18, 19) disposed in an occupant seating area (5) of a seat cushion (2), wherein: each of the switch modules includes a first pressure-sensitive switch (16A, 17A, 18A, 19A) and a second pressure-sensitive switch (16B, 17B, 18B, 19B) that are disposed on a front part so as to be laterally spaced from each other and a third pressure-sensitive switch (16C, 17C, 18C, 19C) disposed on a rear part; each of the switch modules is configured to be turned on when at least one of the first pressure-sensitive switch and the second pressure-sensitive switch is on and the third pressure-sensitive switch is on; and the seat occupancy sensor is configured to be turned on when the switch modules are both on.

The switch body includes: a wiring substrate where first to fourth fixed contact members are formed; and a movable contact member including a pressure receiving part opposite from the second fixed contact member, a first outer edge facing the first fixed contact member, and a second outer edge facing the third fixed contact member. The fourth fixed contact member is formed in a region outside a projection region being a projection of the movable contact member on the wiring substrate and is in a position facing the first outer edge when the second outer edge is moved to a region where the second fixed contact member is formed.

An X-ray fluoroscopic imaging apparatus includes a table, an imaging system including an X-ray source and a detector, and an operation panel unit including a plurality of operation input units. The plurality of operation input units include an emergency stop unit and a stop state release unit. The emergency stop unit and the stop state release unit are provided separately from each other at different positions.

A key structure includes a keycap, a supporting plate, a connecting element, a circuit board and an elastic element. The circuit board is disposed on the supporting plate. The circuit board includes a switch element. A first switch unit of the switch element is formed on a top surface of a first film layer of the circuit board. A second switch unit of the switch element is formed on a top surface of a second film layer of the switch element. When the keycap is depressed in response to an external force, the elastic element is subjected to deformation. Consequently, the first switch unit and the second switch unit are selectively turned on to generate a first key signal and a second key signal.
