Snap action, limit switches, such as the D4NH-1BBC series, consist of a contact block and an actuating head featuring a snap action mechanism. The contact block is the component that houses the electrical contact components and that is connected to the energized circuit. The actuating head triggers the contact action when the device is actuated, using an external mechanical force derived from an object in the environment such as a rod, a cam or a weight.

The D4NH-1BBC series is a snap action, limit switch designed to be used in controlling a variety of mechanical and electrical systems. Its snap action mechanism is designed with a closed-end plunger assembly and a precision molded body. The closed-end plunger is designed to distinguish between very small changes in input and provide efficient switch-action.

The D4NH-1BBC series has flexible mounting options. It can be pre-fitted with a standard turnbuckle for mounting, or can be fitted with a threaded mounting bracket for additional flexibility. The series also offers a variety of different positions for the mounting studs and terminals to create one, two, or three-pole configurations to meet a variety of application requirements.

The D4NH-1BBC series has standard push-button contact types, and a variety of optional contact types. These include: latching contacts, accessories for manual reset, optional built-in contact blocks and other specialized contact types. It also offers various optional connection options from screw contacts to soldered contacts and more. The series also offers long-life options, as well as water-resistant options rated up to IP67, making it suitable for many types of industrial applications.

The working principle of the D4NH-1BBC series is based on the snap action of the actuating head when it is actuated. When the actuating head is actuated, it triggers the contact block, which then changes the connection between the energized circuit and the device. This action changes the status of the energized circuit and can be used to control a variety of mechanical and electrical systems.

The D4NH-1BBC series is ideal for applications such as motor control, automation, process control, lighting control, and more. It is also well-suited for applications that require a quick response, such as emergency stop circuits, door interlocking, limit switches, and more. It is a reliable and cost-effective solution for a wide range of industrial applications.
