Snap action limit switches are devices used in a wide range of industrial, commercial and residential applications. They are usually used to detect the presence of a physical object, such as a container or a gate, and to activate a particular action in response to that presence. WLD2-TH is a type of snap action limit switch that is specifically designed for hazardous locations, such as oil-rigs, mines or chemical plants, where there is a risk of explosion. The WLD2-TH is designed to take action quickly, reducing the risk of catastrophic damage or injury should an incident occur.

The WLD2-TH is a single pole, double throw, or SPDT, switch. It is powered by a 120-volt coil and is activated by a single-action actuator, typically a plunger. When the WLD2-TH is in its rest position, it has three connections: a common, normally open and normally closed. When the plunger is engaged, the switch will shift from one connection to the other. For example, if the normally closed connection is connected to an electrical circuit, and the plunger is engaged, the circuit will be closed and the electrical current will flow.

The WLD2-TH can be used in a wide range of applications, including on/off control for motors, pumps and other machinery, sensing the presence of containers and packages, or to activate alarms or other safety systems. It can also be used to actuate larger machinery, or to control the opening and closing of doors or other access points. In some cases, the WLD2-TH may be used in a positive displacement system, wherein one switch activates the next in line and so forth.

The WLD2-TH is designed to meet hazardous application requirements, and it is UL certified to UL508 standards. It is constructed of a robust die-cast aluminum housing that is protected against dust and liquids, and it is rated for temperatures up to 175° F. The unit is designed to be highly durable and reliable, and it is designed to maintain its performance for millions of operations with minimal maintenance.

The WLD2-TH switch is an ideal solution for industrial applications, particularly those in hazardous locations where safety is paramount. The switch’s robust construction and quick action can help to avoid potential disaster and keep workers and personnel safe in potentially dangerous environments. For these reasons, it is found in a wide range of industrial applications, including oil and gas rigs, mines and chemical plants.
