Snap action, limit switches are commonly used in many applications due to their fast response time, high precision and versatility. These switches are typically used in industrial, automotive and consumer products, including vending machines, HVAC systems, and electronic ovens. The D4BL-3CRA limits switch is part of a family of switches designed to provide reliable and accurate switching performance.

The D4BL-3CRA is a DIN-rail switch with a silver oxide contact and is designed for use in harsh environments. It features a two-piece plastic housing, which protects the electrical parts from shocks, vibrations, and dirt, and provides excellent protection against corrosion. The switch is a snap-action type with a 1/2-inch stroke and a contact gap of 0.008 inches (0.2 mm). The switch is available in either a normally open (NO) or a normally closed (NC) configuration.

The basic operation of a snap action, limit switch is simple. When the actuator is moved, a connection is made between the two contacts inside the switch. This connection may be either normally open (NO) or normally closed (NC). When the actuator is moved back, the connection is broken, and the switch returns to its original position. The switch is designed for either AC or DC voltage applications and is rated to handle a maximum current of 8 amps.

The D4BL-3CRA is designed to provide a high level of accuracy and reliability in a variety of industrial and commercial applications. Its wide range of operating temperatures (-40 to +85°C) and small size make it ideal for tight spaces, and its 1/2-inch stroke allows for precise positioning. Additionally, its silver oxide contact provides superior contact reliability in even the harshest operating environments.

The D4BL-3CRA also features a built-in LED indicator and a self-adjusting dead zone. The LED indicator allows the user to easily check the switch\'s status, while the self-adjusting dead zone provides consistent operation by automatically adjusting to the correct switch timing and action. This ensures maximum precision and repeatability during operation.

The D4BL-3CRA limit switch is an ideal solution for a variety of industrial, commercial, and residential applications. Its small size, wide operating temperature range, silver oxide contact, LED indicator, and self-adjusting dead zone make it the perfect solution for a variety of applications. It is highly reliable, accurate, and versatile, making it an excellent choice for any application requiring a snap-action limit switch.
