Rotary switches have been in existence since the early 19th century and are still commonly used today in a variety of applications. The 44A90-11-1-04N is a family of rotary switches from the American manufacturer, Honeywell. This particular model of switch is available with a range of operating characteristics, including a double pole-double throw (DPST) design, self-cleaning contacts, and two distinct operating positions (ON and OFF).

These switches are primarily used in electrical power control applications, such as main power disconnects, starter/stop/reset functions in industrial machines, HVAC systems, and other controlling functions. In addition to its industrial applications, the 44A90-11-1-04N is also used in consumer electronics devices, such as televisions and radios.

The 44A90-11-1-04N switch is designed with an efficiently designed dielectric arc chamber, allowing the switch to have contacts that are self-cleaning, eliminating the need to regularly maintain the switching contacts. This feature also provides superior performance and helps protect the switch from contact wear due to frequent switching.

The 44A90-11-1-04N rotary switch is operated by manually turning the main shaft connected to the switch. This causes the switch contacts to move from one position to the other. As the switch is turned, the main shaft catches on two levers, which cause the switch plates to open or close, depending on which position the switch is being turned to. This allows the switch to change from a single pole-single throw (SPST) to a double-pole double throw (DPST) configuration.

In their simplest form, rotary switches are comprised of a stationary contact, a rotating contact, a cam plate, and a spring. As the rotary switch is turned, the rotating contact moves into contact with the stationary contact. This completes the electrical circuit which is then able to control electrical power.

The 44A90-11-1-04N rotary switch is constructed from durable materials that are designed to withstand high temperatures and wear. It is certified for use in a variety of industrial applications and is also UL certified, meaning it has been tested and approved for safety.

The 44A90-11-1-04N rotary switch is a versatile switch that can be used for a variety of applications including power control, motor starter, machine start/stop/reset, HVAC control and a variety of other electrical control applications. Its robust construction and self-cleaning contacts make it an ideal solution for any application requiring a reliable, safe and efficient switch.
