EP0989574A2 - Controling serial switch - Google Patents

Abstract

The switch has an illumination and monitoring arrangement for visual display of operational readiness and for state monitoring. The illumination and monitoring arrangement is mounted in the upper part (1) of a multi-part switch socket (2) with two lighting holders (3), each with an associated actuating element (4) and light output point (6).

Description

The invention relates to a series switch with a lighting and Control device according to the preamble of claim 1.

From DE 37 28 749 A1, a socket is known, the cover of which Extension has a glow lamp with contacts for power supply is arranged. These contacts are connected to the contact apparatus of the socket and indicate the operational readiness of the socket by means of the glow lamp.

Furthermore, from DE 38 28 177 C2 a lighting and control device for a safety socket, which in conjunction with a surge protector both the operational readiness of the socket, as well as the functionality of the Overvoltage protection displays. To this end, the known invention has two Provide lamps in the form of a separate plug-in unit on the safety socket is stuck. A lamp shows the operational readiness of the socket and the other lamp indicates the functionality of the surge protection.

Starting from this prior art, the invention is based on the object also to create a lighting and control device that is so constructive is that they are not only visually the operational readiness of a series switch displays, but also the switched state of each individual actuator of the Series switch. This object is achieved by the characterizing Features of claims 1 to 5 solved. The series switch according to the invention can in a simple manner and in connection with an additional neutral terminal in the Switch bases for visual display are formed, which makes an immediate Detection and assignment of an accident is made possible.

The series switch according to the invention is explained and described below with reference to an embodiment shown in the drawing. It shows:

Fig. 1:

partially a section through a series switch according to the invention, the section line being guided through an actuating member;

Fig. 2:

partially in section a side view with rocker switch, and a plan view of the series switch and two actuators greatly enlarged with each light exit point;

Fig. 3:

partly in section, a side view of the series switch without rocker switch, and in a top view with a separate lamp holder, this being shown as a separate part in different representations.

Since the basic structure of series switches is known, are only in the drawing the parts required for the invention are shown, or are only these parts with one Provide reference numerals.

1 to 3 is the lighting and control device according to the invention shown, which is designed as a device placed in a series switch. This Device consists of two illuminant receptacles 3, which are in the upper base part 1 a switch base 2 are arranged. In these two lamp holders 3 the necessary illuminants 5 can be placed for optical display.

As can still be seen from FIG. 1, when the actuating member is plugged in, between the Illuminant 5 and the light exit point 6 in the actuator 4 a light-guiding Element 7 arranged. This arrangement makes a highly visible one in a special way Light emission achieved at the light exit point 6 in the actuators 4. The Illuminant receptacles 3 in the upper base part 1 also allow the inclusion of one separate illuminant carrier 8, provided that special illuminants 5 are used goes (Fig. 3). Since normally the known contact apparatus of a series switch for the Connection of an optical display is not equipped with the invention Device installed in switch base 2 still a separate neutral terminal 9 to the Ensure the supply of the optical display.
