Rotary Switches

Rotary switches have been used since their invention more than a century ago in a variety of applications, from controlling the flow of electricity to selecting the programming options on a cable box. A popular example of the rotary switch is the 44M30-09-2-04N.

Application Field of 44M30-09-2-04N

The 44M30-09-2-04N is a two-pole, four-position rotary switch rated for 250 volts, 10 amps AC or 14 amps DC. It is designed to be used indoors or in dry, dust-free environments and is spray-resistant to greater than 2000 PSI. It is often used in applications such as within home alarm security systems, regulator circuits, portable equipment and automotive electrical applications.

Working Principle of 44M30-09-2-04N

The 44M30-09-2-04N is a double-throw switch, meaning that it has two sets of contacts: a set of normally open (NO) contacts and a set of normally closed (NC) contacts. When the switch is in the “off” position, the NC contacts are in an open circuit and the NO contacts are in a closed circuit. When the switch is in the “on” position, the NC contacts are in a closed circuit and the NO contacts are in an open circuit.

The switch also has two poles, meaning that each contact can be used to control two independent circuits. When the switch is in the “on” position, one of the two circuits is in a closed circuit and the other circuit is in an open circuit. When the switch is in the “off” position, both of the circuits are in an open circuit.

The 44M30-09-2-04N can be used in a variety of applications, from controlling the flow of electricity in a circuit to selecting specific settings on an electronic device. It is often used to control the flow of electricity in an appliance, actuate an electronic device or open and close a circuit. It can also act as a selector switch for choosing options on an electronic device, such as selecting the programming options on a cable box.

The 44M30-09-2-04N is a reliable, durable and versatile switch that can be used in a variety of applications. It is designed to be used indoors or in dry, dust-free environments and is spray-resistant to greater than 2000 PSI. It is a popular choice for those looking for a reliable and versatile rotary switch.
