Rotary switches are a popular and versatile type of switch. A typical rotary switch may have multiple positions in which a contact type is closed or open, depending on the position of the knob. The 44US30-01-4-03S is a particular type of rotary switch. This article will discuss the application field and working principle of this switch.

The 44US30-01-4-03S is a 3 pole rotary switch with a maximum current rating of 30A. It is typically used for applications such as motor control, including AC/DC motors, blowers, frequency controllers, and more. It is compatible with both UL and CSA certification, making it a popular choice among industrial equipment designers. The housing material is typically either chromate steel or phenolic, with varying actuator options available. The terminals are coded for simple wiring.

The 44US30-01-4-03S features a knob which is used to rotate between positions, either clockwise or counterclockwise. The knob is attached to a cam plate with multiple contacts. As the knob is rotated, each contact is either opened or closed based on the position of the cam plate. This depends on the switching mechanism design and is usually indicated by a typographical representation of the switch, such as “OPEN-OFF-OPEN” or “ON-OFF-ON”.
