Rotary Switches

A rotary switch is an electrical switch with multiple positions. It is also known as a selector switch or rotary selector switch. It is most commonly used for changing electrical functions in various applications, with each position providing a different electrical connection. This type of switch is typically used to control the on/off switching of electrical devices or in some cases the step-by-step tuning of equipment.

09P30-05-1-03N Application Field and Working Principle

The 09P30-05-1-03N rotary switch is a selector switch with single pole and triple throw (SP3T) contacts, rated for 30A and can handle 125/250 VAC. It is commonly used to control lighting, motors, and a variety of other applications. The 09P30-05-1-03N switch works by rotating the head, which then moves the selector plate at the top of the switch with three contact pins underneath the plate. Each pin is connected to one of the three terminal screws at the bottom of the switch, which are connected in turn to the external electrical circuits.

When the head is rotated, the plate moves, selecting one of the three contact pins that is connected to the external circuit. When one of the contact pins is selected, an electrical connection is made between the external circuit and the selected contact pin, allowing the flow of electricity. When the head is rotated to a different position, the plate moves, breaking the connection between the contact pin and the external circuit, and then creating a new connection between another contact pin and the external circuit.

The 09P30-05-1-03N rotary switch is ideal for applications that require switch changing in confined spaces, as it is easily operated without requiring excessive effort. The switch construction ensures long life and reliable performance, making it suitable for reliability-critical applications. It is also suitable for use with a variety of electrical devices and circuits, including motors, lighting, and others.
