Abstract: A push button switch, particularly a power supply switch, has contacts (4, 5) attached to a housing and a movable contact bridge (8) which is moved by means of a spring plunger (10'). A spring switching mechanism (26) transmits force between the spring plunger (10') and a manually-actuated switch actuator (22'). The switch actuator (22') is alternately latched and unlatched by a locking linkage (27, 28) which alternately holds the switch actuator in "switched-on" and "switched-off" positions when the switch actuator is repeatedly pushed. Additionally, a switching rocker (51) is provided between the switch actuator (22') and the spring plunger (10') to improve switching action. The switching rocker (51), at the beginning of "switching-on" and "switching-off" operations, forcibly carries the spring plunger (10') in its respective switching direction through a partial path of its contact stroke (H).

Abstract: In an apparatus for the transfer of information in motor vehicle traffic between a fixed-position transmitter-building element near a roadway and a receiver arranged in a vehicle, the transmitter-building element emits a coded information signal and the receiver of the vehicle driving past the transmitter-building element displays information from the information signal in the vehicle. In order to make shielding measures unnecessary, with an uncomplicated supply of energy to the transmitter-building element and small construction costs therefor, the transmitter-building element (1) is built into roadway pavement (12). The energy necessary for transmitting the information signal is received by the transmitter-building element (1) from the vehicle (13) which is driving above it.

Abstract: A push button switch, particularly a master switch, has housing-affixed contacts (4, 7) and at least one contact bridge (8, 9) movable by a spring plunger (10). A spring-switching mechanism (24, 25, 26) is operatively coupled between the spring plunger and a manually-movable sliding switch, or switch actuator, (22). A guiding, or sliding, locking linkage apparatus for the sliding switch (22), which includes two locking parts, a first of which is a track (27) and a second of which is a follower lever (28) for engaging the track. Upon alternate depressions of the sliding switch, the sliding switch alternately moves between "on" and "off" positions. In order to prevent damage to the locking apparatus upon a pulling of the sliding switch in a direction opposite to a direction of depression of the sliding switch, the first and second locking parts release from the housing to follow movement of the sliding switch.

Abstract: A remote control unit radiates signals of operated program selection keys (3) via an infrared transmitter circuit (10, 11, 12). In order to simplify the selection of one of several TV programs for the user, the remote control device has a receiver circuit (18 to 23). The latter detects picture signals of the TV programs to be selected via program selection keys (3). A storage unit stores these picture signals. To each of the program selection keys (3) on the remote control set a picture display (6) is assigned. A control circuit (24, 29, 30) distributes the picture signals from the storage (25) cyclically to the picture displays (6).

Abstract: An electric testing device is provided for the final testing of vehicle combination instruments. The vehicle combination instruments comprise display means (1-7) consisting of segments, a display control in a microcomputer (8) for activating the segments as a function of measured values, for analog measured values an analog-digital converter (14) arranged in front of the display control, and possibly an input network (13) arranged in front of said converter. The testing device and combination instruments are intended for final testing in a plurality of final test phases. Tolerance values of a critical display value are stored for each measurement value in the microcomputer (8). These tolerance values can be compared, in a first final test phase of a manually actuatable final-test operating mode, with a simulated measurement value which is fed into the microcomputer via the analog-digital converter and possibly the resistance network.

Abstract: An electric display device for a vehicle, particularly a motor vehicle, has at least one display instrument, at least one memory which stores a desired display value and can be set with the display instrument in a test phase, as well as switch means for the switchable dividing of pulses of a variable to be displayed, in particular a speed of rotation. In order to be able, during the test phase, to check a division which has been set, the memory stores at least two desired display values. The output of each of the stored desired display values to the display instrument is switchable by the switch, which also effects the switching of the division. In this way, during the test phase, only the desired display value which corresponds to the setting of the switchable division of pulses is shown.
