Rotary switches are a type of switch that commonly uses a circular knob which is rotated to make or break an electrical connection. The 56P30-01-1-04N is a single pole double throw (SPDT) rotary switch, which, depending on the position of the knob, can connect the input terminal to either of two output terminals. This makes it a useful switch for applications requiring the selection of one signal output from among two sources or the changing of one signal path to another.

The 56P30-01-1-04N is constructed as a sealed unit of high-grade plastic that is rated for up to 3A of current at 300 Volts AC and is designed to offer long life, low cost and reliable operation in a variety of applications. The 56P30-01-1-04N can be re-engaged up to 1 million times, making it an ideal choice for high-reliability applications.

The 56P30-01-1-04N has a wide range of application possibilities, including test and measuring instrumentation, multiplexers, switching between different power sources, switching between different input signals, monitoring systems and controlling motor speed.

The working principle of the 56P30-01-1-04N is essentially simple. The input terminal connects to the common (shared) terminal when the knob is in the center position and can either connect to the normally open terminal (NO) or normally closed terminal (NC) as the knob is turned. The contact between the common and the output terminal is made by a movable contact attached to the knob, which moves across weak-contact wiper bridges in order to close the correct connection.

In order to ensure that the switch maintains continuity, all of the switch’s contacts are self-cleaning, meaning that they are designed to erase any corrosion or carbon deposits that build up over time. The switch also features a dust seal that helps to keep dirt and other particles out of the contact area, thus prolonging the life of the switch.

The 56P30-01-1-04N rotary switch offers a reliable, long-lasting and cost-effective solution for a wide array of applications. It is capable of withstanding large amounts of current, is equipped with self-cleaning contacts and includes a dust seal to keep its contacts free of debris. Its versatility and durability make it an ideal choice for a variety of applications.
