Description

The present invention is a remote timer switch for lighting systems of any kind, such as stair lighting, etc., in which one of the magnetic core is spring-influenced Rocker plate, lever or the like. is rotated, from which two spring-operated toggle levers be controlled in such a way that the contacts in the excitation and lamp circuits are closed and opened as a result.

According to the invention, the under action a spring freely rocking to both sides mounted disc, lever or the like. By means Stops of any kind by being under the influence of an air brake or other Hemmwerk standing magnetic core forcibly rotated back and forth for the purpose of this, the toggle lever by further To fold down the stops of the disc. As a result of this design, it is only a simple matter of tearing off the contacts in the mains circuit Mechanism is required and an inexpensive design with a reliable effect is achieved, in which failure is as good as impossible. The apparatus can be proportionate are heavily burdened.

Such a remote time switch for lighting systems is arbitrary in the drawing Art shown in an exemplary embodiment, namely shows

In the magnetic coil α , the magnetic core b is arranged displaceably in such a way that it is pushed upwards when the current flows through the coil α. The core b is under the influence of a spring, by means of which it is slowly pulled back downwards. The stroke of the core b can be adjusted by a known screw c. A disk d or the like is attached to the end of the core b. A disk e or the like is loosely rotatably mounted to the side above the magnet coil α and serves to control the two toggle levers f, g. The control disk e is designed as a rocker. This is achieved in that it is under the influence of a spring h , one end of which is connected to a stationary pin k below the axis of rotation i , while the other end is connected to the disk e above the axis of rotation. If the disk e is now rotated and the spring h comes to stand a little beyond axis i , the disk quickly snaps to the right or left side over to a stop. The two toggle levers / and g, which are under the influence of springs m and η, are rotatably mounted in the bearing rail /. The springs m and η are so connected to the levers f, g that the latter snap up or down as soon as they come out of their horizontal position. In their rest position, the

at f, g on contact t in the control circuit, while in the raised position they are both temporarily on the lamp contact. On the front of the disk e , two drive pins o, p are attached, between which the disk d of the magnetic core b engages. On the back of the disk e there are three protruding driving pins q, r and s . The pin ί is an extension of the pin o. When the core b goes up, the disk e is rotated by the pin ο. At the same time, the toggle levers f, g are also turned up from the disk e through the pins e., Q, r so that they are

»Apply 5 to lamp contact u and close the circuit to the lamps. When the core b slowly descends, the disk e is turned back by the pin p and first the toggle lever / by the

so pin r swung back, so that it rests against the control contact ί again. If the disk is suddenly turned back further, the second toggle switch g is torn off from the lamp contact by the pin, and the lamps go out. Instead of the rocker disk e , a rocker lever or the like could also be used. The whole switch is mounted on a plate.
The function of the timer is as follows:

As soon as a push button or the like in the control circuit is closed and the coil α is excited, the core c is thrown upwards so that the disk d rotates the disk e by means of the pin 0 and the toggle levers f, g of the pins q, r and close the lamp circuit, while the excitation circuit is interrupted at contact ί. The disk e then rests against the lever g with the pin r. The core b then slowly goes back under the influence of a spring, and the disk d rotates the disk e at the pin ρ. About half the rotation of the disk e takes place slowly, corresponding to the lowering of the core b. Even with this partial rotation, the toggle lever / is taken along by the pin r and the contact t in the control circuit is closed again. As soon as the disk e is later turned so far that the spring h has passed the center of the axis i , it goes back quickly and completely and jerks the toggle lever g away from the lamp contact into its starting position by means of the pin j. The burning time of the lamps therefore corresponds to the time in which the core b recedes. Because the control contact t is closed again at the beginning of the reverse rotation of the disk e , the lighting time can be extended by closing a push button in the remote control circuit before the previous burning time has expired. This prevents it from getting dark between each actuation of a push button, which cannot always be avoided with the known time switches.
