    摘要： The disclosure provides a door switch that improves visibility. The door switch includes an actuator and a sensor. In addition, the door switch is installed so that when a door is closed, a surface of the sensor and an opposite surface of the actuator are in contact with or close to each other, and when the door is open, the surface of the sensor and the opposite surface of the actuator are separated from each other. The actuator outputs a detection signal. A display part for indicating a reception state of the detection signal is formed on the surface of the sensor. The surface of the sensor has a non-opposite region, wherein the non-opposite region is at least a part of the display part not opposite to the opposite surface of the actuator in the reception state.

    摘要： A target device for use with a switch device of a proximity switch has a wireless receiver means (6) for detecting and receiving a first pulsating signal (A) with a first carrier frequency (f1) from a nearby transmitter module (5), demodulating (6, 7) the received signal, and if a superimposed digital signal is present, inverting (9, 10, C4, and Q1) the superimposed received digital signal or, if the superimposed digital signal is absent, passing the existing energy through (10). The target device also has a wireless transmitter means (12) for modulating and sending the inverted pulse train if this exists by the second carrier frequency (f2) to the receiver switch unit (13). Additionally, the target comprises functionality to transmit the carrier frequency (f2) continuous and unmodulated where a continuous and unmodulated carrier frequency (f1) is present. However, upon existence of the pulsating signal only one of the receiver (6) and the transmitter (12) receives or transmits a signal at a given time.

    摘要： The present invention relates to a switching device for generating a switch signal, a reading device with the switching device and a method for the communication between a reading device and a transponder (T). The switching device includes an antenna (4), which with the help of an adapter circuit (AN) is adapted to a given resistance, and a measuring bridge (1), which includes two voltage dividers connected in parallel. The resistance acts in one of the voltage dividers and in the case of a change of the resistance the measuring bridge (1) generates the switch signal. This means when a transponder reaches the detection range of a reading device having the switching device, an additional impedance is coupled in, which acts on the measuring bridge (1). This change is recognized and leads to the generation of the switch signal.

    摘要： An arrangement for monitoring first and second relatively movable parts in which an actuator is connected to one of the first and second parts. The actuator includes a transponder. A sensor is connected to the other one of the two parts and has a receiver circuit with a receiver coil. A reduction coil is arranged so that its magnetic field can reduce a magnetic field of the receiver coil in a predetermined manner. The transponder touchlessly transmits a bit-coded transponder signal to the sensor when a distance between the actuator and the sensor falls below a predetermined value, and the receiver circuit compares the transponder signal to a stored bit sample for generating a monitoring output signal.

    摘要： Disclosed is a proximity switch provided with an actuator unit and a sensor unit. The sensor unit is provided with an antenna coil, a transmitting circuit which transmits electromagnetic waves at a constant frequency to the antenna coil, a receiving circuit which detects external signals received by means of the antenna coil, and control circuits. The actuator unit is provided with an antenna coil, a power supply circuit which rectifies an electromotive force generated in the antenna coil, and a signal processing circuit which receives power supply from the power supply circuit, performs frequency-dividing to the signals received by means of the antenna coil, and transmits the signals from the antenna coil after the frequency-dividing. The control circuit of the sensor unit has memory for registering the frequency of the signals transmitted from the actuator unit. The control circuit determines whether the actuator unit is in proximity to the sensor unit or not by checking the received signals detected by means of the receiving circuit with the operations of the transmitting circuit and the frequency registered in the memory.
