In materials science, a snap action is any physical device or system having the capability to produce a sudden, rapid response to a stimulus. It is also known as a snap action switch. A limit switch is an electric device used to limit the range of motion in industrial machines, for instance, to prevent over-travel. The D2HW-BL201M combines both snap action switch and limit switch technologies to create a reliable and efficient product.

The D2HW-BL201M snap action, limit switch is designed primarily for use in water and air conditioners, escalators, conveyors, and other such devices using pressure controls and sensors. The product utilizes a pair of pressure-tolerant, double-pole, single-throw (DPST) switches made with high-strength stainless steel, capable of switching up to 30A at 250VAC. It features a spring-loaded plunger as the operating element, and can only be actuated by pushing or pulling it, allowing it to snap into action.

The D2HW-BL201M is composed of three components: the plunger, the switch base and the actuator button. The plunger is the most important part of the switch, since it is the one that will receive direct mechanical force, pushing or pulling the switch into action. It is made of tough stainless steel and is shaped in a conical form to ensure consistent and accurate operation, as well as superior protection from wear. The switch base and the actuator button work together to control the operation of the plunger.

When the actuator button is pushed, the plunger is forced down, and the switch opens, allowing current to flow. When the actuator button is released, the plunger is sprung back up, and the switch closes, stopping the current. This cycle can be repeated multiple times, allowing the switch to operate reliably over time. The plunger can be adjusted to perform at a variety of threshold pressures, allowing it to be used in a range of applications.

The D2HW-BL201M is designed to be used as a control, monitoring and safety switch in a variety of applications. Its snap action, limit switch capabilities make it extremely reliable and versatile, enabling it to be used across a wide range of industries. It is often used in the following types of applications: escalator and elevator controls, speed limiters, conveyor systems, pressure controls and sensors, water and air purifiers, and industrial machine control systems.

The D2HW-BL201M snap action, limit switch is a compact, reliable and efficient product. It provides reliable and accurate performance in a wide variety of applications, and is one of the most trusted snap action, limit switches on the market.
