Device for switching electrical high-voltage currents

The invention relates to a device for switching electrical Heavy currents by means of a weak current controlled Ilelals

It is known that devices that consist of a Stroanets of, for example, 220 V, 50 Hs are fed by means of a low-voltage controlled relay see below, with the control current only a few volts Has tension. The control pulse can, for example, come from a time, photo cell or temperature-controlled electronic Amplifier originate.

arranged, the two positions of which are marked by the letters A and R.

The housing 1 encloses a _{relay 17 - shown schematically in Pig r} 4 - the coil of which is connected to the connection elements 13-14. The relay 17 has a movable contactor l8 which is connected to the relay armature and which can optionally be connected to the contacts 19, 21, the contact 19 being a normally open contact and the contact 21 being a normally closed contact. The contactor 18 is connected to a line 22 which connects the plug pin 9 to the socket 3 inside the housing 1. The normally open contact 19 of the relay 17 is connected to the contact of the changeover switch 16 assigned to position A, while the normally closed contact 21 is connected to a contact of the changeover switch 16 which corresponds to its position R. The contacts of the changeover switch and the relay 17 can also be bridged by a line 23 which contains a capacitor 24 serving for radio interference suppression. As can be seen from Flg. 4, the connector 8 of the power plug 7 is connected to the socket 4 of the socket 2 via a line 25, while the protective contacts 6 and 12 are connected to one another by a line 26.

The device described is operated as follows: The housing 1 is plugged into the socket with its mains plug 7 plugged into a heavy current network. At sockets 3 »4 a high-voltage consumer to be switched by means of a mains plug, z. B. a radio or a lamp connected. The connecting elements 13, 14 are connected to a low-voltage control device connected, for example a timer or a light barrier.

The relay 1% and the changeover switch 16 are initially in the positions shown in FIG. If a low current (z. B. 7.5 V) flows through the relay 17 from the low-voltage control device via the connection elements 13, 14, its contactor 18 switches from contact 21 to contact 19, so that now the circuit from connector pin 9 to Socket 3 is closed. Thus, the heavy current consumer connected to the sockets 3, 4 is supplied with current as long as the relay 17 has control current flowing through it.

With the help of the switch 16 can also be independent of the position of the relay 17, a consumer connected to the socket 2 can be switched on and off.

As can be seen from FIG. 1, a transparent window 27 is arranged on the front side of the device according to the invention. The relay 17 is attached (in a manner not shown) to the base of the housing 1 so that its contacts 3J ₈ 21 auras are visible through the window 27.

If one adjusts to general spark formation by observing the relay contacts, the line 23 and the capacitor 24 can also be omitted, since radio interference suppression is practically unnecessary if the spark formation ceases and a capacitor 24 with a large capacity can be a hindrance when the spark generator is set .

the capacitor 24 can also be connected so that it can be switched off «

The device according to the invention allows, in the manner described, the safe transition of Sehwachstron control devices, e.g. light, temperature or sound controls, electronic circuits, translucent timers, alarm systems, etc., to net-operated devices such as radios, lighting, fans , Motors, exposure devices la photo laboratory, alarm sirens etc. The device lfiAt sioh z. B. designed for an alternating voltage of 220 V and an amperage of 10 A · A pocket lamp battery is sufficient as a control power source. A particular advantage of the device according to the invention lies in the fact that it is simply inserted as a (Schuko) intermediate plug into the supply line to the device to be switched.

Although the socket 2, the plug 7 and the connection elements 13, IH are permanently connected to the relay 17 in the described embodiment example, it is easily possible to design one or more of these parts independently and separately and via a cable connect with the parts arranged on the foot.
