Plastic Push Button Switch

The following is a detailed introduction to the LA38 series button switches produced by Yijia Company:

application

The LA38 series button switch is suitable for use in electromagnetic starters, contactors, relays, and other electrical circuits with AC 50Hz (or 60Hz), voltage 380V and below, and DC voltage 220V and below, for line control purposes. The LED illuminated button is also suitable for situations that require light signal indication, providing intuitive visual feedback for operators and facilitating the judgment of equipment operation status.

Model Naming and Meaning

key-lock selector two selector switch 2 position rotary

key-lock selector three selector switch 3 position rotary

The model naming of LA38 series button switches follows a certain pattern. For rotary switches, “X/21” represents second gear self-locking, “X/31” represents third gear self-locking, “X/22” represents second gear self resetting, and “X/33” represents third gear self resetting. By using different model suffixes, button switches with different functions and operation modes can be distinguished to meet various complex control requirements.

TECHNICAL INDEX

-LED light button has a long lifespan of up to 30000 hours, reducing the frequency of replacement due to indicator light damage and lowering maintenance costs.

-Rated working voltage of signal lights: covering various voltage specifications such as AC and DC, including 6V, 12V, 24V, 36V, 48V, 110V, 220V, as well as AC 220V and 380V. It can adapt to different electrical system voltage requirements and has strong universality.

-Color: There are multiple colors to choose from, including red, green, yellow, white, blue, black, etc. (with light button but no black). Different colored buttons can be used to distinguish different functions or states, for example, red is often used for emergency stop buttons, green is used for start buttons, etc., in accordance with ergonomics and safety regulations in industrial design.

-Life indicators: The mechanical life of the button is up to 100 × 10 ⁴ times, and the electrical life is 50 × 10 ⁴ times; The mechanical lifespan of the knob is 20 × 10 ⁴ times, and the electrical lifespan is 10 × 10 ⁴ times. The high lifespan index means that the product can withstand frequent operation and long-term use, with good durability and reliability.

-Other indicators: Insulation resistance ≥ 50M Ω, which can effectively prevent leakage and ensure safe use; The contact resistance is ≤ 50m Ω, ensuring smooth current transmission and reducing energy consumption and heat loss. The diameter of the installation hole is 22mm, making it easy to install on various control equipment panels.

Product Features

-Appearance and Material: The product has an exquisite appearance, with some button heads using metal aluminum caps, and the metal button switch housing using high-quality materials such as stainless steel copper chrome plating. It not only has good corrosion resistance and wear resistance, but also enhances the overall texture and aesthetics of the product. The contacts are made of silver alloy. At the same time, there are various styles to choose from for the button head, and it comes with a removable protective film that can protect the button surface from damage during transportation and installation.

-Installation and maintenance: Some models, such as the LA38 series button, use patented structures that can be quickly disassembled with just one press and two pulls. The LA38M series elevator industry specific button adopts a modular combination structure, with a single piece buckle contact module and a light-emitting module, making installation and maintenance convenient and structurally reliable.

operating mode

-Self momentary: After the self resetting button is pressed, when the hand is released, the button will automatically pop back to its original position, and its normally open contact will be connected when pressed, and disconnected when the hand is released. This button is suitable for situations such as jog control, for example, in situations where it is necessary to briefly start the device for debugging or single operation.

-Self latching-cabinet latch: After pressing the self-locking button, it will maintain its current state, that is, after the normally open contact is connected, releasing the hand will not disconnect, and the button needs to be pressed again to return to its initial state. Commonly used in control circuits that require maintaining device operation status, such as the start button of the device. When pressed, the device starts and maintains operation until the stop button or other related operation is pressed to reset it.

application area

-In the industrial field, it can be used to control the start, stop, and forward/reverse rotation of various motors, contactors, relays, and other equipment in industrial automation production lines; In the control of mechanical equipment, it can achieve various function switching and emergency stop control of the equipment; In the power system, it can be used for operation control and signal indication of equipment such as switchgear and control cabinets.

-In the field of home furnishings, it can be applied to smart home systems to control the switches of lighting, curtains, household appliances, and other devices; On the control boards of some household appliances, applications similar to button switches can also be seen, enabling the selection and control of electrical functions.

-In the business field, it plays a role in the control of automatic door control systems, lighting control systems, and various commercial equipment in shopping malls and supermarkets; In the hotel room control system, it is used to control the lighting, air conditioning, television and other equipment in the room.
