Rotary switches are commonly used to control applications where a variable control or selection of multiple positions is required. The 51A30-01-2-04N is an industrial rotary switch designed to function in harsh environments, such as industrial environments, while providing reliable and safe operation.

The 51A30-01-2-04N is a 2-pole, 4-position switch suitable for high-load AC and DC applications. It features a double-break contact design and offers a complete switching program; the switching action on this switch is independent of the type of load applied. The switch’s contact arrangement is such that any contacts can be connected with any other contacts.

This rotary switch has a die-cast metal housing with a metal end plate. With a wide range of mounting hole sizes and threaded terminal screws, it is designed to fit various wiring needs. It has UL, IEC and CSA approval, making it suitable for worldwide use.

The 51A30-01-2-04N is rated for 20A/250V AC and 20A/30V DC. It is a multi-pole rotary switch that features a single-turn construction, which allows for a maximum rotation of just one turn. Its multithreaded shaft with a keyway ensures anti-rotation, so that the switch cannot be accidentally moved from its set position. The switch also features a cam action for audible and time-saving alignment.

The 51A30-01-2-04N rotary switch works on the principle that two switches are engaged and disengaged when the selector knob is rotated. As the selector knob is rotated, one switch is engaged while the other switch is disengaged. This action creates a series of electrical connections and disconnections, which can be used to control the operation of various devices. To prevent arcing, the switch must be designed with an arc shield which contains a spring-loaded carbon arm.

The 51A30-01-2-04N rotary switch is typically used in industrial and commercial applications such as motor control, machine and communicating devices, lighting control, and more. Its reliability, durability, and switchability make it an ideal choice for many applications.
