D2QW-C003H Datasheet/PDFSnap action, limit switches are electrical switches that use a spring to perform an action with a snap of motion. D2QW-C003H is one of these snap action, limit switches which has become currently one of the most popular snap action, limit switches due to its unique design and a range of applications.
The D2QW-C003H uses two electrodes with a toggle switch design that features a metal armature mounted between a pair of contacts. The armature is a metal rod that moves against the contacts, which when pushed by an actuating force tripping a spring, causes the armature to vertically move and quickly break contact between the pair of contacts. This quick movement is called a "snap action." The contacts can be a pair of normally-open or normally-closed contacts.
The D2QW-C003H is typically used for sensing an over travel limit or for detecting the presence of an object. When installed in an over travel limit application, if the object passes the set limit and presses the armature against the switch, the contacts will close and a current will flow when the armature snaps back again. In a presence detect application, the contact will remain open unless the armature is pushed. If a current is applied, when the armature snap back, the current will flow again.
The D2QW-C003H is a versatile snap action, limit switch and has a wide range of uses in consumer, industrial and commercial applications. It is commonly used to activate water faucets and to hold water pressure in households. It can also be used in sensitive industrial applications, such as controlling the movement of sensitive robotic systems and in laboratory equipment. It is also used in many consumer products such as cameras, TVs and game consoles.
The D2QW-C003H is also used in a variety of commercial applications, such as in cash registers, ATMs and vending machines. It is also found in elevators, escalators and automatic doors. In the medical field, it can be used in devices such as patient beds, wheelchair lifts and other medical devices which require precise, snap action movements.
The D2QW-C003H is a highly-durable, reliable and cost-effective snap action, limit switch that is well-suited for a wide range of applications. It is easy to install and require little maintenance, making it an ideal switch to use in any situation that requires quick, accurate and reliable switch action.
