Special switch

It is not possible for me to provide information about a "special switch" without more context or specific details about what you are looking for. There are many different types of switches that may be considered "special" depending on their specific function, design, or application. For example, a switch that is designed for use in a hazardous environment may be considered a "special" switch because of its unique construction or safety features. Similarly, a switch with a unique form factor or actuation mechanism may be considered "special" because of its unique design. It is important to provide more specific information so that I can provide a more accurate and helpful response.
