A rotary switch is a switch in which the contacts are changed when the rotor is turned. The 44HGS45-02B04N is a type of rotary switch designed with a dc contact rating of 0.5A/12v with a minimum of 10,000 cycles.

The 44HGS45-02B04N is primarily used in low voltage DC applications due to its low rated current; some of its common applications include lighting fixtures, motors and small home appliances.

This rotary switch consists of two main components: the fixed parts, which are generally referred to as the rotor, and the movable parts, consisting of the switch actuator, or knob, and the contact blocks which contain the electrical contacts.

The typical working principle of the 44HGS45-02B04N is relatively straightforward, consisting of an input specified contact, to which power is connected, and an output specified contact, from which the power is passed. The input contact allows the power to be connected when the switch is in its idle or disconnect position. When the actuator or knob is rotated, the contacts are moved and the output contact is opened, thereby disconnecting the circuit.

The switch can be set to operate in either a maintained or momentary contact mode. In a maintained contact mode, electrical power is transmitted continuously as long as the actuator remains in a certain position; in a momentary contact mode, the switch provides electrical power only while the actuator or knob is being operated.

In addition to its low voltage DC application, the 44HGS45-02B04N switch can also be used in some AC applications due to its insulation resistance and surge strength of up to 500v. The switch is also equipped with a dust cap and a switch guard which helps to prevent accidental engagement. The switch is UL, CUL, CE and RoHS certified, providing protection against electrical shock, making it safe for use in household and industrial applications.

In conclusion, the 44HGS45-02B04N is a reliable and cost-effective rotary switch designed for low voltage DC and AC applications, offering users a wide range of features including multiple contact modes, a dust cap, a switch guard and UL, CUL, CE and RoHS certification.
