71B30-02-1-05N

A rotary switch is a type of switch with a rotating actuator. 71B30-02-1-05N is a particular rotary switch that comes from C&K, a major manufacturer in switches and relays markets. It is used extensively in electrical and electronic applications.

The 71B30-02-1-05N is a standard 8-position rotary switch in the C&K 71 Series DIP switches family. It is sealed for reliable performance and operates with a rotational life of more than 500 cycles. The switch is SPST-NO rated with a 10A contact current rating and a 120VAC, 28VDC maximum electrical rating. It has a maximum temperature operating range of -55C to +105C.

The 71B30-02-1-05N can be used to provide on/off switching function and a selection of multiple options and settings. It can be found in many applications such as computer peripherals, telecommunications, test and measurement equipment, audio/visual systems, HVAC and home appliance control, aviation instrumentation, solar power, medical, and various industrial applications.

The working principle of the 71B30-02-1-05N is fairly simple. When the knob is turned, the actuator is rotated and the contacts are closed. The contacts remain closed as long as the actuator is held in the turn position. When the switch is returned to its original position, the actuator is released, allowing the contact to be opened and power to be turned off.

In summary, the 71B30-02-1-05N from C&K is a reliable 8-position rotary switch that can handle high current and temperature ratings. It is suitable for many applications requiring an on/off control, selection of multiple options, or settings. Its simple working principle makes the switch an ideal choice for a variety of applications where accuracy and reliability are needed.
