Rotary Switches

A rotary switch is a mechanical switch in which a lever is rotated to make and break electrical contact. They are commonly used to control electrical equipment such as appliances and lighting fixtures. The common type of rotary switch is the 44HBS30-01B09N.

Application Field

The common 44HBS30-01B09N rotary switch is a three-pole switch commonly used in automobiles, and as a household power switch. It is rated for a maximum of 15A250V in residential and commercial applications. It is also suitable for use with fan motors and other AC applications. It can also be used as a switch for low voltage DC applications such as 12V lighting.

Working Principle

When the lever is moved to one of the three poles on the rotary switch, the contacts of the switch are engaged. As the lever is rotated to the second and third poles, the corresponding contacts are also engaged. The 44HBS30-01B09N rotary switch uses a nipple to act as an index, marking the start and end of each pole and helping to ensure that the correct contact is engaged when the lever is moved. When the lever is in its off position, the contacts on all three poles are disengaged, preventing any electrical current from flowing.

Conclusion

The 44HBS30-01B09N rotary switch is one of the most common types of rotary switches. It is used in all types of applications from high voltage AC to low voltage DC. It uses a simple lever action to make and break contacts at each pole, providing reliable control of electrical equipment.
