DB2521V Datasheet/PDFPushbutton switches are specialized components for the operation of circuits and machines, the most common being manual devices used to operate light fixtures, computer related electronic systems or other components within and across power distribution networks. They are commonly used in commercial, industrial, and residential applications as they provide a convenient and secure means of controlling power to a variety of system functions.
The DB2521V is a type of pushbutton switch specifically designed for use in hazardous and harsh environments. This model features a high-current rating of 21A with a switching voltage of up to 125V. It is sealed and certified to international guidelines, with an LED indicator ensuring secure operation without the risk of contact failure.
In terms of application field, DB2521V pushbutton switches are typically used in military, medical, and industrial environments. Their working principles relate to the contact formed when two metal parts (such as a base and a stem) come into contact with each other. When in contact, the contact creates a temporary bridge between two electrical elements, allowing current to flow through the circuits and allowing for a controlled switch.
The DB2521V switch is a waterproof nickel-plated bronze alloy contact switch, consisting of two micro-rods, one short and one long. The long rod is secured to a base and a stem, the latter being joined to the switch by a push-button actuator. The two micro-rods form the electrical contact with the switch contacts on either side when the stem is pushed in.
The DB2521V\'s robust construction also offers quick action, reliable performance and a long working life. It is designed with IP67 sealing to enable use in even the harshest environments, making it suitable for use in a wide range of applications.
The DB2521V is a cost-effective and reliable choice for a wide range of industrial, medical and military applications, particularly in harsh environments. With its high-current rating and robust construction, it provides a secure means of controlling a variety of system functions.
