093101-2-03N

Rotary switches, or rotary variable switches, are a type of switch composed of multiple rotary contact elements, often referred to as “ports” or “wipes.” The elements can be stationary contact elements that rotate with a shaft or drum, or movable contact elements that move with an actuator lever. Rotary switches come in various configurations, including several sections, single pole, multipole, and are designed for use in a variety of applications, including switching lights and appliances, controlling systems for air conditioning, and controlling motors.

093101-2-03N is one of the rotary switch series developed by Cirrus Logic. It is a double-pole, four position rotary switch with a contact rating of 5A at 250VAC. The series has shorting and break-before-make contacts, and has been optimized for switching high voltage AC applications. The body of the switch is made of glass-filled nylon, and is UL94-V0 rated. The 093101-2-03N has a travel distance of 90° and an operating force of 125gF.

In terms of applications, 093101-2-03N can be used to switch high voltage AC equipment such as lamps, ceiling fans, ovens, range hoods, and motor controlling units. This series is also suitable for applications requiring frequent switching under relatively low power levels. It is commonly used in industrial automation and laboratory equipment, as well as in the home for controlling lightswitches, thermostats and other AC-powered appliances.

The working principle of 093101-2-03N rotary switches is based on impedance and contact wear. When the switch is actuated, the contact pressure of the contact terminals is increased, resulting in increased contact current and reduced contact resistance. This decrease in resistance is necessary for the switch to operate properly and ensure a safe connection between the device and the power source.

093101-2-03N rotary switches are designed to be low maintenance and highly reliable. The switches are built with multiple contact positive stops and adjustable wipers that reduce the drain on the surrounding wiring and ensure a consistent connection. The contact surfaces are formed to reduce contact wear and give the switch longer service life. The 093101-2-03N is also rated IP55, protecting it from dust, oil, grease, and other contaminants.

Overall, 093101-2-03N rotary switches combine the simple and robust construction with reliable performance, which makes them an ideal option for switching high voltage AC equipment. They are capable of providing reliable, consistent and cost-effective operation with minimal maintenance.
