He scolded

The present control relates to a slide switch with at least one contact spring for connecting contacts ₈ arranged next to one another, the ends of the contact spring being bent by more than 180 degrees and resting on the side surface of a recess in an insulating material carrier.

In a known slide mount, an insulating material carrier is fastened to the slide of a button »In the insulating material carrier several recesses are arranged next to each other _s in each of which there are two resiliently opposing ₉ made of wire or band-shaped material © springs _? the ends of which are bent in the manner of a half ellipse = blade contacts can be inserted between the opposing springs,

In contrast, the present leuerung is characterized gekennzeieh _»s iiet that the iSnden are formed arc-shaped and that the support locations of the - ends of the recess in the radius thereof adapted ° sindο

While the spring action ends solely by the compression of the bent ^ in the known springs into existence _s comes will by the spring according to the innovation thereby improving ₉ that the circular arc-shaped ünden be rolled up upon loading of the spring through the guide in the support points. This creates a torque ₉ which increases the contact pressure in the middle part of the spring, so that a very uniform contact pressure is now achieved along the contact surface

The use of wire-shaped material for the contacts 2 _{0 is also advantageous}

The contact springs 6 bind according to a preferred embodiment. play in the area of the bent bindings provided with recesses 10 5 to achieve a soft spring characteristic »

It is advantageous to arrange the _{3 contact springs 6 on opposite sides of the insulating material carrier 3 and} to fix the contacts on both sides of the contact springs 6 in an injection-molded or pressed housing no significant heating forces, as with one-sided arrangement of the contact springs 6 ₀
