LW26 Series rotary switches

Introduction

Working conditions

- Ambient temperature Do Not exceed 40℃, and the average temperature,measured over a period of 24 hours,Do Not exceed 35;
- Ambient temperature Do Not less than -5℃;
- Should Not be installed above 2000m above sea level;
- A clean environment was required.

Designation

Use as control switches  

1: Rotary switch (Cam switch);
2: Product code;
3: Rated thermal current;
4: Code of the degree of rotation;
5: Character code;
6: Code for contact of the switch;
7: Number of layers.

Re: Character code represent the rotating type, for instance, we have limited movement, spring return and limited movement with spring return.

Use as control switches  

1: Rotary switch (Cam switch);
2: Product code;
3: Rated thermal current;
4: Motor Rating (3 phase AC);
5: Usage Code: 1 Q for start and run;
                          2 N for reversing;
                           3 S for 2 speed;
                          4 SN for 2 speed and reversing;
6: Number of layers.

Re: switches in this category normally rotate at 60 . And the SN normally rotate at 45.

Use as control switches 

1: Rotary switch (Cam switch);
2: Product code;
3: Rated thermal current;
4: Number poles: 2 poles, 3poles, and 4poles.

Re: switches in this category normally rotate at 60.

Classification

- Classified by utilization:

(1)Cange-over switch;
(2)Motor switch;
(3)Control switch;

- Classified by operation:

(1)Limited movement;
(2)Spring return;
(3)Limited movement with spring geturn;

- Classified by contact system:

(1)Switches with limited movement could have 12 layers in maximum (for 32A and below), and for 63A and
    above could have 8 layers in maximum;
(2)Switches with spring return could have 3 layers in maximum;
(3)Motor switches could have 6 layers in maximum.

Technical parameters

Re: Neutral;
Re: The power under AC-23A AC-3 AC-4 are in three phase three pole, and the divider represents the power under single phase two pole.

Mechanical life

- Mechanical life without load: 60x104times, operation frequency is 120 times/h;
- Mechanical life with load: 20x104times under AC-15, 6x104times under DC-13, operation frequency is 300 times/h.
