An apparatus for providing a switch mechanism comprises a housing and a pressure sensitive device mounted to the housing. An actuator is moveably connected to the housing to enable the actuator to move along an axis towards and away from the pressure sensitive device. A resilient member has a first end connected to the actuator and a second end connected to the pressure sensitive device.

A sensor device for detecting at least one physical variable, comprising a housing, at least one sensor element arranged in the housing, at least one circuit board arranged in the housing and comprising a circuit arrangement, and at least one input device arranged on the housing for carrying out input operations which are processed in the circuit arrangement to influence the sensor properties, is characterised in that the input device, to realise a touch-sensitive effect, comprises an actuation area, which is arranged on a housing wall and is permeable to electric fields, and a capacitive area, which is arranged on the circuit board or is formed as part of the circuit board, and in that the circuit board is arranged in the housing such that the capacitive area lies directly below the actuation area.

Disclosed is an integrated interconnect cable component for allowing the operation of dielectric shift sensor elements with a variety of control monitors associated with pressure switch based patient alarm systems. The interconnect cable component may be used for connecting a dielectric shift sensing mat (associated with a patient monitoring system) with any of a variety of different pressure switch based control unit module as utilized in conjunction with patient occupancy alarm systems. The interconnect component includes an integrated driver, sensor, comparator, calibration, logic circuit; a relay activation circuit; and a power supply (battery). The cabled component takes the dielectric shift measured across the contacts for a sensor mat and drives a relay activation circuit accordingly. The relay activation circuit in turn provides the on/off switch condition that the existing pressure switch monitor circuit expects to see at the connection cable.

Disclosed is a touch window according to the present invention in which a FPCB, an IC, a function key area for a connection with a touch sensing sensor electrode are all formed in a single printed circuit board and are formed not to be exposed to the outside by receiving the printed circuit board in a lower part of a transparent window, thereby being capable of simplifying a structure of the touch window.

In the present invention, a capacitance-type switch is provided with an operation plate and an electrode plate. The operation plate forms operation surfaces operated by the touch of a fingertip F (operation body) of a user. The electrode plate is disposed on the side of the operation plate opposite the operation surfaces. Furthermore, the capacitance-type switch is turned on and off in response to the change in capacitance caused between the fingertip F and the electrode plate. In addition, a high-permittivity material is disposed in an outer circumferential section of the electrode plate, the high-permittivity material having a higher permittivity than the operation plate. It is possible to improve the sensitivity of the capacitance-type switch while minimizing malfunctioning.

A control panel for a vehicle. The control panel includes a decorative layer and a control assembly. The decorative layer has a visible face and a rear face opposite to the visible face. The control assembly has a front face and a rear face opposite to the front face. The front face of the control assembly faces the rear face of the decorative layer. The control assembly is fixed to the decorative layer and includes a support film, a pressure sensor and a light-emitting diode. The pressure sensor and the light-emitting diode are printed on the support film.

A touch-sensitive glass barrier has a conductive coil affixed to the first side of a glass barrier, a capacitor connected to the conductive coil to form a resonator, and an inductance-to-digital converter (LDC) connected to drive an alternating current through the resonator. The LDC determines whether a conductive target has touched the second side of the glass barrier at a point opposite the conductive coil; and responsive to determining that the conductive target has touched the second side of the glass barrier at the point, provides a signal.
