Description

(B 116247

The subject of the invention is a momentary switch with the contact closure and opening movement of the expanding spring spring. The essential feature of the invention is that in the switch a contact-closing roof-shaped spring or double roof spring without a fixed connection is displaceably mounted on control elements, which is controlled by a switching element that grazes over its apex is pressed to jump into the contact closed and open position.

On the drawing are some Ausfüh approximate examples of the subject invention reproduced.

Fig. 8 a wall switch with a simple, roof-shaped spring spring reveals.

In the end walls 2 and 3 of the housing ι sit according to Figs. 1 to 6, the connection contacts 4 for the line. According to Fig. 1, the spring spring rests with its legs 5 'or with its connecting parts against the right contact 4 and is held in this position by the projections S, which lie against the free legs 5 "of the spring spring 8 press the free spring legs 5 "at the same time against an extension 13 of the contact 4 ', in which a spring pin 12 is guided. The housing 1 has slots 9 through which bolts 10 engage and into the inner part 7 of the contact piece. These bolts 10 are in the for

Switching serving handle ir, for example a slide ring attached, so that when you move the ring ii the inner switching element 7 is taken. The switch is operated as follows:

In the position of the parts shown in Fig. 1, the current passes from the + contact 4 the spring 5, the pin 12, the extension 13 and the contact 4 'to the line. The projections 8 of the switching element 7 are behind the vertex 6 of the spring on the free legs 5 ″. To switch over, now the ring 11 is initially moved into the position shown in Fig. 5, in which the apex 8 of the switching piece 7 and the apex 6 of the spring 5 lie on top of one another, so that the Contact closure still exists and the spring 5 is clamped to the extreme. As soon the ring 11 is now moved a little further to the right, the spring 5 jumps by sliding the apex 6 on the apex 8 of the contact piece 7 with large Force and speed past and slides into the position shown in Fig. 6. She rips so suddenly the contact from, so that immediately there is a momentary switching. she presses the pin 12 against the action of its spring of lesser strength in ' the extension 13 into it, while the pin 12 it in turn in a right-fitting position to inner switching element 7 holds so that it remains correctly set for the next circuit.

The embodiment of Fig. 7 is based on the same principle, only the contacts are 4 "moved to one end of the housing 1, while the spring 5 'or 5" with its connecting part against the projecting into the housing 1 lugs 14 of Contacts 4 "places. To simplify the manufacture of the entire switch, the Slots 9 'of the housing on one side completely carried out, so that the ring 11' and the Switchover inserts 8 'can be manufactured from one piece and can be inserted while from the other Switch face ago any striker 15 produces the end. :

In the case of the switch according to Fig. 8, a simple spring 5 rests on a conductive, Plate 20, with its bracket 18 after the con! bar 4 'there and the bridge bracket 19 after Contact 4 brings you to the end. The conductive piece 20 with the contact 4 'is isolated from the conductive piece 17 with the contact 4 by an insulating piece 21, which is bridged by the bracket 19 during the circuit (see dash-dotted point) will. A roller 23) is used for switching, which is mounted in a bracket 24, which is his Has pivot point at 23. This spring 5 also suddenly jumps as soon as the roll reaches the apex 6 leaves the spring, from the position shown in solid lines in the dash-dotted or reversed t. The release of the spring can also be carried out in a similar manner when using spiral and helical springs, the application of which is not shown, rules. The advantages of the facility are many. First is contrary to all so far switches used, including those in which switching pieces rolling along springs for switching and sliding pieces were used, a momentary break of the contact secured, while on the other hand again in the switching position a firm contact closure through the compression of the spring is forced. Furthermore, the utmost simplicity of installation is required very few individual parts, makes most of the otherwise necessary screws dispensable and is in addition to all of them being inexpensive to manufacture, they are also inexpensive to assemble.
