LW26 Series rotary switches
Introduction
- LW26 series rotary switches represent the most advanced rotary switches. We currently have six models,current rating up
to 160A, suitable for wide variety of applications;
- LW26 series rotary switches are suitable for: on-off of an electrical circuit, change-over of electrical circuits,motor switch,
instrument switch, and main switch;
- LW26 series rotary switches comply with: GB 14048.3, GB 14048.5, and IEC 60947-5-1;
- LW26 series rotary switches have six current ratings: 20A, 25A, 32A, 63A, 125A, and 160A. LW26-20 and LW26-25 has the
fingerproof terminals, which offered an extra advantage;
- LW26 series rotary switches have wide variety of applications, they are ideal substitution for LW2, LW5, LW6, LW8, LW12, LW15, HZ5, HZ10, HZ12, and other rotary switches and cam switches;
- LW26 series rotary switch has two derivatives: LW26GS Pak-lock type switch (63A and below) and LW26S
Key-lock type switch (32A and below), which could be installed in instruments to prevent the equipments from mis- operations.
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.

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.
Order procedures
In order to avoid any mistake during the order, customers should follow the right procedure’
The following information should be supplied:
- Contact diagram, we have published«Contact diagram for LW5D series rotary switches», the diagram applied for LW5D could applied to LW26 series as well. And we have selected sime typical diagrams in this catalog;
- Type of escutcheon plate;
- Type of handle;
- Character code and code of degree of rotation;
- Rated current;
- Quantity. |
