Analyzing Electrical and Thermal Conductance in a Contact Switch
A contact switch is used to regulate whether or not an electrical current is passing from a power source and into an electrical device. These switches are found in many types of equipment and they are used to control, for example, the power output from a wall socket into a device when it is plugged in; the currents passing across the circuit board of a computer; or the electricity powering a light bulb when the switch is flipped on. Because of their prevalence, simulating contact switches is a fundamental step in designing electronic applications. Since the concept used in their design remains much the same even as more complex components are implemented, a simple model can be used to provide a basic understanding of how a contact switch works. We can find such a simulation in our Model Gallery, and can use this model to explore the mechanical, electrical, and thermal behavior of the two contacting parts of the switch.
