metal button with blue indicator

A 19MM metal push button switch with indicator is an electrical component with a diameter of 19 millimeters, made of metal materials and equipped with an indicator light. It is widely used in various electrical control systems. Here is a detailed introduction: Common Features Size and Material: The installation hole diameter is usually 19mm, and the shell is often made of stainless steel, which has the characteristics of corrosion resistance and durability, and can present a sleek industrial appearance. Indicator Function: It is equipped with an indicator light, such as a yellow LED ring or other colored LED lights, which can clearly display the activation status of the switch, making it easy for users to observe whether the switch is in the on or off state. Operation Mode: There are usually two types: momentary and latching. The momentary switch is only connected when pressed and disconnected when released, which is suitable for applications such as trigger control and reset functions; the latching switch will remain in the on or off state after being pressed until the next operation. Electrical Parameters: The rated voltage and current vary depending on the model. For example, there are products with a rated voltage of 250V AC/36V DC and a rated current of 2A/3A, which can meet different electrical connection requirements. Protection Level: Many 19MM metal push button switches with indicators have a high protection level, such as IP67, which means they are completely protected against dust and can withstand immersion in water up to 1 meter deep, suitable for use in harsh environments such as outdoors or industrial sites. Application Scenarios Industrial Control: It is used in the control panels of various industrial equipment to control the start, stop, and reset of the equipment. Machinery Manufacturing: Installed on machine tools and other mechanical equipment to realize the operation and status indication of the equipment. DIY Electronics: Favored by electronic enthusiasts, it is used in DIY electronic projects to add control and status indication functions. Automation Systems: Applied in automation production lines and other systems to achieve the control and status monitoring of various processes.
