Schurter's snap fit circuit breakers can be assembled from the front of a device without the need for additional fixation from the back. Therefore, these metal switches can be used in applications with limited assembly space or in situations where access to the back of the casing is not possible. This means that these switches can adapt to places where traditional switches cannot be applied.
In addition, this type of installation achieves cost savings by greatly reducing assembly time. The component becomes effective by fitting the force of the switch into the borehole, and the O-ring will be displaced. After inserting the switch into the borehole, the O-ring expands and the switch is fixed in the borehole. It should be noted that there is no flashing on the panel cut, and the drilling diameter must be set within the minimum tolerance range (± 0.15mm from the nominal drilling diameter) to ensure the protection position of the switch. In addition, since the position of the switch is determined by the thickness of the panel, the thickness of the front panel is important. By using sharp tools, the switch can be removed from the front panel. Therefore, switches with this assembly technology are only suitable for applications that are minimally exposed to destructive behavior.
