Rotary switches are electromechanical devices used to make and break electrical connections. The 71BD30-05-1-AJN is a heavy-duty, single-pole, double-throw, multi-circuit rotary switch that is rated for 30 amp continuous use and 60 amps for overload. This switch can be used for a variety of applications, but its primary purpose is to disconnect and reconnect the power supply of an electrical circuit in order to turn the circuit on and off.

The 71BD30-05-1-AJN rotary switch has two types of circuits – an alternating action circuit and an Off-On-On circuit. The alternating action circuit is used to quickly switch between two sources of power. This is useful in applications such as an emergency light switch, or an irrigation system that needs to switch between battery or mains power with a single switch. The Off-On-On circuit is a three-position circuit, which is used when there is a need to manually override a particular device or operation. This is useful in applications such as controlling a motor speed, or switching between fan or heating elements.

The 71BD30-05-1-AJN rotary switch is built with a solid-state contactor mechanism that features a highly reliable and durable surface mount construction. This switch is designed to have no sparking at the contact points, and its contact mechanism is hermetically sealed to prevent the ingress of dirt, dust, and moisture. In addition, this switch can handle diverse operating temperatures from -40°C to 105°C, making it suitable for a wide range of applications.

When it comes to the working principle of the 71BD30-05-1-AJN rotary switch, it is based on the rectification of alternating current supplied to the contact points. When the switch is in the OFF position, the contact points are insulated and no current can flow through the circuit. When the switch is moved to the ON position, the contact points are energized and current can pass through the circuit and switch will be closed to power the device or equipment. This is how the rotary switch turns devices and equipment on and off.

As indicated, the 71BD30-05-1-AJN rotary switch is a great choice for heavy-duty applications that require switching between two sources of power, or manually overriding a device or operation. This switch can handle continuous use up to 30 amps, and overload up to 60 amps, making it suitable for industrial, commercial and residential use. Plus, it is designed to provide a long service life with minimal maintenance.
