Right-to-Left Support
The Switch fully supports right-to-left (RTL) language locales (Figure 1). In order to turn on the RTL support, you should set dir=rtl to the html or body element or at least to its parent element (Figure 1). You can also use the direction:rtl CSS property.
<div style="direction: rtl;">

</telerik:RadLabel>
<telerik:RadSwitch runat="server" ID="RadSwitch1" Checked="true" AutoPostBack="false">

<ToggleStateOff Text="نه" />
