Rotary Selector Switch

What is Rotary Selector Switch

Rotary Selector Switch are a type of multi-functional electrical switch that can move in circular motion as the word rotary suggests and stop in several positions. It consists of a rotating shaft which has a rotor and moving contact or disk that is attached to a contact plate. The rotation of the shaft or disk causes the contacts to either open or close, which in turn either completes or breaks the circuit with the contact housing.Generally used to control the working of different circuits with a single switch, rotary switches can also be widely used as a great alternative to push button switches.

How to Choose Rotary Selector Switch

Actual needs

The central idea of purchasing a rotary selector switch is to meet the actual needs of work and life. Therefore, when choosing, you must start from the actual situation and do not blindly choose expensive products. If you are not familiar with rotary selector switches, you can consult professionals for guidance, so that the selected rotary selector switch meets your actual needs.

Appearance

After clarifying the central idea of the purchase, you can start to choose the rotary selector switch from the perspective of details. When choosing, you can first look at the appearance of the multi-position rotary switch. The appearance is not only for beauty, but also because people are directly in contact with the external multi-position rotary switch when operating. If the appearance quality is too poor, it will also cause great harm to personal safety. Moreover, if the manufacturer of the multi-position rotary switch does not pay attention to its appearance, then its internal structure may not be much better.

Internal structure

After looking at the appearance, you also need to look at the internal structure. The various components inside the rotary selector switch must be closely matched. When the external switch is manually turned, the internal components react quickly, and there will be no jamming or jumping. At some solder joints, there must be no loose welding or too rough welding. Only such an internal structure is reasonable.

Design

The design of the rotary selector switch should be reasonable. From the appearance, moving or pressing the button should be easy and agile, and the response should be relatively fast. From the inside, the various lines should be clean and orderly, so that people can know the internal structure at a glance. If it is too messy, then such a rotary selector switch must be of poor quality and is not recommended for purchase.

Working Principle of the Rotary Selector Switch

Rotary Selector Switch is a switch that controls the opening and closing of the main contact by rotating the handle. There are also two types of rotary switch structure, unipolar, single-position structure and multi-pole, multi-position structure. Single-pole, single-position rotary switches are often used together with rotary potentiometers in operation. Multi-pole, multi-position rotary switches are mostly used to switch operating conditions.

The working principle of the Rotary Selector Switch is: change the resistance value within a range, and then there is a contact switch. This is the switch for the old TV and radio. The current electric fan has several gears, and several sets of lead wires connected to the fan winding. The speed is changed by changing the number of coils. The principle is similar to that of a potentiometer.

Rotary Selector Switch Wiring Guide

1. Due to the low on-off capability of the rotary switch, it cannot be used to break the fault current. When the motor is used to control the forward and reverse rotation, the reverse connection is not allowed after the motor is completely stopped;

2. When the power factor of the load is low, the capacity of the rotary switch should be reduced, otherwise it will affect the life of the switch; if the power factor of the load is less than 0.5, it is not suitable to use the HZ rotary switch because of the difficulty of extinguishing the arc;

3. There are many ways to connect the rotary switch, and it is necessary to select products of corresponding specifications according to actual needs. It does not have overload and short circuit protection. If the circuit requires the above protection, it should be installed separately at the same time;

4. The operation should not be too ordinary, usually should not exceed 300 times per hour. Otherwise, the mechanical wear of the contact is too fast, and it is easy to leave the metal powder in the contact gap and cause poor insulation.
