Snap Action, Limit Switches - D2HW-BL201H Application Field and Working Principle

The D2HW-BL201H is a snap action, limit switch which is used to detect the position of movable parts of machines. This particular model of limit switch uses a single pole double throw (SPDT) with a normally open configuration. It is designed to detect the movement of objects in a variety of applications including mechanical switches and pneumatics.

The D2HW-BL201H consists of three primary components: a switch body, a plunger and a contact block. The switch body is made of corrosion-resistant stainless steel and houses the plunger and contact block. The plunger is a cylinder that extends from the switch body and is activated when pressure is applied to it. The contact block is a metal piece that is connected to the plunger and housed within the switch body; when the plunger is activated, the contact block is pushed outward, closing the circuit and providing a signal.

The D2HW-BL201H works on the principle of snap action. When the plunger is pressed, it snaps into the closed position, creating an audible click. This instant switch closure creates a fast switching action that is reliable and consistent, providing assurance that the switch has operated correctly. The snap action mechanism is also designed to provide electrical insulation and superior shock and vibration resistance.

The D2HW-BL201H can be used in a variety of applications. It is often used to control the movement of mechanical actuators, such as valves or pumps, as well as to monitor the position of chassis or other components in automation systems. It can also be used to control electrical power supplies and actuate alarms or signals in backup systems. Furthermore, it is commonly used in the automotive industry, as well as in materials handling systems, industrial machinery and medical equipment.

The D2HW-BL201H is a reliable and rugged snap action, limit switch. It is designed for use in harsh conditions, providing accurate and consistent performance in the most demanding applications. It is available in a wide range of sizes, configurations and operating temperatures to meet the needs of any application.
