Rotary switches are essential components for a variety of electrical purposes, such as controlling electric current. The 59M18-03-1-05N is a common type of its kind and its application field and working principle can be expounded below.

Basic Description and Function

The 59M18-03-1-05N is a three-pole, single throw (3PST), rotary switch model supporting various voltages and a maximum of 11A. The terminals of the switch body have a lever welding structure design which allows for more firm and secure connection. The product has an insulation resistance of 1000MΩ and contact resistance up to 50mΩ. Its operating temperature range is between -25°C and +85°C and the screw used for connection is M4×6.

Application Field

The 59M18-03-1-05N rotary switch can be applied in the following two major fields:

• Industrial Field: Industrial production or process operation often requires the need of switch adjustment, such as the adjustment of a thermostat. The 59M18-03-1-05N rotary switch is used in this case as it provides quick an accurate switching.
• Consumer Field: Many home and office appliances such as fans and air-conditioners also use rotary switches due to its relatively low price, excellent performance, and durability. This switch is also widely used in audio equipment and other communication devices.

Working Principle

The 59M18-03-1-05N rotary switch works by providing connection between the input and output poles. The switch has a built-in silver alloy contact and a contact changing structure with a rotary shaft design. When the switch is in its off position, the contact is separated from the input and output terminals and no current can flow. When the switch is turned on, the contact changes its position and connects the input and output terminals, thus completing the circuit and allowing for current flow.

Advantages and Drawbacks

• Advantage: The 59M18-03-1-05N rotary switch is a cost-effective and efficient solution for many applications, both in terms of providing reliable switching and for its small size and low profile.
• Drawback: The switch offers little protection against voltage surges, thus an external electric protection device may be needed for some scenarios.

59M18-03-1-05N rotary switches are a suitable choice for both industrial and consumer applications due to their performance and small size. To choose the right product it is important to consider the specific needs of the application and all safety standards.
