Abstract: An electronic switch has an input terminal, an output terminal and an electronic switch unit between the input terminal and the output terminal controlled by a control circuit which extends from its anode to its trigger and is under the control of an actuator which the user can operate directly or indirectly. There is a current limiter resistor in series with said control circuit. The value of the current limiter resistor is less than the value of the voltage on triggering of the electronic switch unit divided by the minimal trigger current needed by the electronic switch unit for such triggering. It is in the order of 40 ohms at most, for example. Applications include controlling a load without generating spurious harmonics which are a problem on the mains supply.

Abstract: In a method of automatically controlling a lighting load to which are delivered alternately forced turning on instructions and forced turning off instructions, according to the result of comparing the brightness measured in a given area and particular brightness thresholds, the brightness threshold used to deliver a forced turning on instruction, hereinafter called the comfort threshold, is left for the user to determine. In a normal operation phase, i.e. after an initiation phase, the brightness threshold used for delivering a forced turning off instruction is the sum of this comfort threshold and the brightness difference between the brightness measured before the previous forced turning off instruction and the brightness measured immediately after that forced turning off instruction. Applications include automatic control of fluorescent tubes with a non-electronic ballast.

Applications include self-contained emergency lighting units.

Abstract: A two-way switching circuit for connecting a supply power to a load comprises two electronic switches connected to each other. Each of the two electronic switches includes two electronic switch units connected to each other. Each of the two electronic switches has a control circuit including a common actuator selectively connected to both of the electronic switch units thereof for alternately turning on the respective electronic switch units. A first of the electronic switch unit of each of the two electronic switches is connected to each other and a second of the electronic switch units of each of the electronic switches is connected to each other, whereby switching circuit is thus adapted to connect a power supply to a load when both of the first electronic switch units or both of the second electronic switches are on.

Abstract: A two-wire power supply switch connected in series with a load between two poles of an alternating current mains electrical power supply conventionally includes a main triac between two terminals of the switch which is turned on by the conduction of an optotriac with a time-delay relative to the zero crossing of the voltage between the switch terminals determined by the breakdown voltage of a series of Zener diodes. The switch includes a power supply unit with a rectifier bridge connected to one terminal directly and connected to the other terminal via a capacitor. An auxiliary triac shunting the capacitor is turned on by the optotriac on each zero crossing of the voltage between the switch terminals. This optimizes conditions when the switch is open and when the switch is closed separately.

Abstract: A switch mechanism has a conductive mobile contact carrier with two lateral branches pivotally engaged with a central hub. The lateral branches of the conductive mobile contact carrier are continuous with its middle branch, each being joined to the latter by a large radius elbow, and the conductive mobile contact carrier bears on the output contacts through its lateral branches. The output contacts are near the central hub so that the lateral branches of the conductive mobile contact carrier are subjected to a local transverse self-cleaning movement when it comes into contact with the output contact. Applications include single-throw and double-throw switches.
