D2HW-BR243ML

Snap Action, Limit Switches are mechanical devices used for signaling, flashing, and actuating. They typically feature contact elements, such as springloaded plungers, which are actuated based on physical force. When the force is applied, the contact elements mechanically snap open or closed, providing a momentary indication of the contact state. Examples of such devices include microswitches, limit switches, and overtravel switches.

The D2HW-BR243ML is a snap action, limit switch that can be used in a variety of applications requiring momentary or intermittent contact. The device features three or four independent contacts, depending on the model, which can be configured for either single-poled or double-poled configurations. The construction of the device is based on a plastic moulded body with the contact elements, plunger, and return spring enclosed within.

When actuated, the plunger is forced against the inner contact element, which momentarily closes the circuit. As the force is released, the returned spring pulls the plunger away from the contact element and the circuit is once again open. The response time, also known as the snap-action delay, is dependent on the plunger force, return spring, and the electrical contacts.

The D2HW-BR243ML can be used in a variety of applications, including controlling an automated system and providing indication of the switch\'s contact state. With its increased switching capacity and improved repeatability, the device can be used in high-vibration environments, as well as in hazardous and explosive locations.

The device also offers a variety of contact configurations, including normally open (NO), normally closed (NC) and change-over (C/O). These contact configurations are used for simple on/off control and indications, as well as for more complex circuit control. The contact force of the device is adjustable via the use of the supplied set screws. This allows the device to be used for a variety of applications, where precise contact control is required.

The D2HW-BR243ML is a highly reliable, mechanical contact switch. Its simple yet robust construction offers improved switching capacity, repeatability, and a versatile contact configuration. The device is used in a wide range of applications, where it provides on/off control with precise contact control.
