D2HW-BL271M

D2HW-BL271M is a type of snap action limit switch typically used in various industrial applications. It is typically used to detect the position of a mechanical actuator, or to detect the opening and closing of a door or window. The switch is also suitable for use in security systems and for controlling locos, robots and other motorized devices.

The limit switch is constructed from a zinc die cast body, with a snap action silver alloy, making contact with a nickel-plated steel base. The base incorporates a steel actuator, which is connected to the cable that runs the switch. The switch is designed to have a longer life, able to operate in harsh environments, and has a UL rating, making it suitable for use in industrial applications.

The switch has two basic working principles. The first principle is that when the switch is pressed to the side, a circuit is closed. This means that when the switch is pressed, it will close and turn on whatever device is connected to it. The second principle is that when the switch is released, the circuit will remain open and keep whatever device connected to it in its on state.

The switch is available with either a normally open or normally closed connection. This means that when the switch is in its neutral or off state, it can be used to either turn on or switch off whatever device is connected to it. The switch is also available in either a momentary or maintained configuration. The momentary type of switch allows the user to press the switch and then immediately release to either turn on or switch off a device.

The switch is also available in different mounting styles, such as a vertical or horizontal, depending on the type of application. The switch is also available in various wire leads with various switches, including screw down, push button, roller lever, and plug in. The switch is also available with a variety of options for safety, such as an overload switch, or a switch lock.

The D2HW-BL271M is a versatile and reliable snap action limit switch, perfect for a variety of industrial applications. It has a durable, long-lasting construction, and is available with various connection options and mounting styles. Its long life, UL rating, and versatility, make it an ideal choice for a wide range of industrial and commercial applications.
