19mm Momentary Switch

The 19mm momentary switch is an instant control electrical component independently developed and produced by YIJIA. Its core feature is that the contacts remain conductive only when physically pressed, and return to the default open or closed state after release, without the need for manual reset. The product is specifically designed for the 19mm standard installation aperture and belongs to the compact switches commonly used in the industrial control field. It comes in two configurations: normally open (NO) and normally closed (NC), and can flexibly adapt to different circuit design requirements. Relying on YIJIA's over twenty years of switch research and development experience, this product has independent intellectual property rights. In terms of structural design, it combines innovation and practicality, and is a basic industrial control component that balances operational convenience and performance stability.

Product Function

The core function of the 19mm momentary switch is to achieve instantaneous circuit connection and disconnection as well as instantaneous control of equipment. It is widely used in various industrial scenarios and equipment accessories. Specifically, it can be used to trigger alarm signals, start or stop mechanical equipment, point control of production lines, switch lighting status, and other scenarios requiring brief operations. It is compatible with control consoles, control cabinets, instrument boxes, automated production lines, automotive control systems, and other types of equipment. The high-brightness LED indicator light it is equipped with can clearly display the working status of the switch, enhancing operational safety and convenience. At the same time, its high current carrying capacity and high protection performance can ensure the stable operation of the equipment in complex environments and reduce the occurrence of faults.

Usage Notes

When using the 19mm momentary switch, it is necessary to first confirm that the installation aperture size matches the opening size of the equipment to avoid installation looseness and affect the usage; during installation, it is necessary to distinguish between the normally open and normally closed contacts, and correctly connect the wires according to the control circuit requirements to prevent reverse connection from causing the equipment to fail to work properly. During use, it is necessary to avoid exceeding the rated current of the switch (maximum 18A) to prevent contact burnout; avoid frequent violent pressing to avoid shortening the mechanical lifespan. This switch is suitable for use in an environment ranging from -20℃ to 60℃. Avoid long-term exposure to high temperature, high humidity, and strong corrosive environments. If used outdoors or in harsh workshops, it is recommended to choose a custom model with IP67 waterproof rating. Daily maintenance requires regular cleaning of dust and oil stains on the switch surface to ensure stable contact of the contacts.

Material Advantage

YIJIA strictly controls the selection of materials. The 19mm momentary switch is made of stainless steel, which is formed through precise stamping process. It has a solid texture, is resistant to wear and corrosion, and can effectively withstand dust, moisture and minor impacts in industrial environments. It won't deform or fade over a long period of use. The internal core contacts are made of high-quality silver alloy, with a contact resistance of ≤ 50mΩ. They have excellent conductivity, strong arc resistance and can significantly extend the electrical lifespan of the switch. The insulation components of the switch are made of high-quality engineering plastics, ensuring reliable insulation performance and effectively preventing leakage hazards, thus ensuring safe usage. The LED indicator light is selected as a high-brightness and long-life model. It has a lifespan of up to 50,000 hours, emits light evenly, and comes in various colors such as red, blue, green, yellow and white, suitable for different indication requirements.
