Rotary Switches

A20415RNZQE application field and working principle

A20415RNZQE rotary switches are versatile components that can be widely used for various switching applications. The most common application areas include audible and visible alarm systems, industrial automation and control, motor run and stop control, process control systems and motor speed control. Additionally, they are used to control lighting, relays and motors in hazardous control panels and plant operating rooms.

A20415RNZQE switch consists of a rotary switch with an insulated contact, and consists of a drive gear, contact plates and movable contact arms. The contact arms form the output contacts of the switch, and the stationary contact plates provide the inputs. When the drive gear is turned, it moves the contact arms to engage different contact plates and thus produce a variety of switching actions.

The drive gear is usually connected to an external actuator or motor, with the shaft connected to a lever or armature that transfers rotary motion from the actuator to the switch. The actuator can be either manual or automatic, depending on the requirements of the application. The actuator can also be programmed to set the rotary switch at a desired switch position.The most widely used A20415RNZQE switches are classified according to the number of poles and throws available for each switch type. A single pole, double throw (SPDT) switch assembly has one switch pole, dual contact arms and a single throw. A double pole, double throw (DPDT) switch assembly has two switch poles, four contact arms and two throws.

A20415RNZQE switches are available in a variety of contact configurations, including normally open, normally closed and changeover. Depending on the application, the switches can be either single-throw (ST), double-throw (DT) or three-throw (TT). The number of throws and contact combinations in A20415RNZQE switches can range from one to six and up to sixteen. The contact material in A20415RNZQE switches is usually silver or gold plated, depending on the contact ratings specified by the user.

A20415RNZQE rotary switches are typically used with removable keys that mechanically engage the switch, such as DIP lock or slotted key switches. These keys help to ensure the switch is installed correctly. Additionally, the switches are available with various mounting options, including panel, base, wall and surface mount.

In conclusion, A20415RNZQE rotary switches are versatile components that are used for a variety of switching applications. They can be used for audible and visible alarm systems, industrial automation and process control systems, and motor run and stop control. They are available in a variety of contact configurations, and can be mechanically engaged with removable keys. Additionally, the switches are available in a variety of mounting options.
