Torque Test of Rotary Switch

　　Rotary switchIt can replace the rotating pulse generator, which replaces the traditional resistance potentiometer simulation function, which is usually applied to the front panel of the instrument and the man-machine interface of the audio control panel. Rotary switches use quadrature optical encoders as purely digital devices that replace analog potentiometers. These rotary switches are similar in appearance to traditional or resistive potentiometers, but the internal structure of these rotary switches is completely digital, using optical technology. As with traditional incremental encoder products, there are two orthogonal output signals (channel A and channel B), which can be directly connected to the encoder processing chip.

The operation of the handle gives people a good sense of operation experience. The handle is easy to adjust and operate. The encoder handle can produce many functions, such as the handle of the oscilloscope. A handle can replace 0-9. It is very convenient to use.

How to choose the right encoder handle, typical encoder switches have half-wave and propagation points, no button switches and switch points, and 12-segment, 24-segment, 30-segment and other specifications. Whether there are electric signal switches, half-wave propagation, how many files will affect our quick selection according to our needs, the hand feeling in operation, and the torque of the handle.

A typical handle twist, handle feel test is as follows.

1. Torque peak detection

2. Torque valley test

3. Torque Friction torque test

4. Detect the twist feel.

In the torsion tester PS-2205S, after the software sets the function, it will automatically calculate all peak torque, valley torque, friction torque and hand feeling.

Equipment characteristics

1. The box body is treated with electrostatic paint, the whole machine has reasonable design, firm structure, safe and reliable operation, and meets the test requirements.

2. Adjustable rotation diameter, number of times, speed and counterclockwise time, humanized design;

3. The replaceable test fixture conforms to various types of product tests and has wide applicability.

Whether it is domestic homemade machines or imported machines, you can seeRotary switchof existence. Because the main function is to switch other function signal action. It cannot be replaced by a normal button. Because the early mechanical technology has not improved. At that time, the switch product was large in size and required jumper welding, which was very complicated in manufacturing and assembly.

Since the previous production of CNC machines, for the sake of machine safety and durability, the oil refining machine team is now dominated by switches made in Japan. Many machines have been using the first generation switches normally for more than 20 years, which shows that their products are quite excellent. Many other peers or self-employed in order to repair, in order to save costs, the use of imitation Japanese products, the quality is uneven, please do not use. Because the replacement of the switch parts is still relevant.
