Contact Switch

Application ID: 4119

This model illustrates how to implement a multiphysics contact. It models the thermal and electrical behavior of two contacting parts of a switch. The electrical current and the heat flow from one part to the other only through the contact surface. The contact switch device has a cylindrical body and plate hook shapes at the contact area. There, the thermal and electrical apparent resistances are coupled to the mechanical contact pressure at the interface, which is solved by the model.

This model example illustrates applications of this type that would nominally be built using the following products:
