Snap action, limit switches have been an integral technology for industrial automation since its invention in the 1940s. Due to their versatility, versatility and affordability, these switches are used in a variety of automation applications and processes, from safety switches and door opening systems to position and pressure control systems. Today, several types and features of snap action and limit switches exist, providing ideal solutions for all types of industrial automation needs. One such switch is the D2HW-BR222MR snap action and limit switch.

The D2HW-BR222MR is a spring-loaded, push-button type snap action, limit switch. It is available in two and three-pole versions with a wide range of configurations and options. Some of the features of the D2HW-BR222MR include a silver-plated contact material, encapsulated construction, push-button actuation and silver-coated wiring flex cables. These features provide a robust and reliable switch for many harsh industrial automation applications.

The most common application for the D2HW-BR222MR is industrial door opening systems. The switch is typically mounted on the frame of a door at the point of operation. When the door is opened and closed, the switch actuates accordingly. When the switch is actuated, it triggers the door opening system to activate the proper functions: opening, closing, locking and unlocking.

Another popular application for the D2HW-BR222MR is position and pressure control systems. In these systems, the switch is typically used to control a position or a pressure relief system. The switch is actuated to open or close a valve or to trip a circuit breaker, in order to control the position or relief pressure of a system.

The working principle behind the D2HW-BR222MR snap action and limit switch is fairly simple. It is usually actuated when pressure is applied to a plunger at the center. The plunger within the switch contains a coil spring and as pressure is applied to it, the plunger is forced down against the spring and the contact points of the switch come into contact and complete the circuit.

When the pressure is released, the spring returns the plunger to its original position, breaking the contact points and deactivating the circuit. This snapping action of the switch is what gives it its name: the snap action, limit switch. It is also this feature that gives it its versatility, as it is capable of switching circuits with a coarse action or with a fine action, depending on the application.

The D2HW-BR222MR is an ideal choice for harsh industrial automation applications due to its robust construction, push-button actuation and silver-coated wiring flex cables. With its versatility and affordability, it is the perfect solution for a wide range of industrial automation needs.
