Can be preferred with NPT or Metric threading.

What Are Ex-proof Electrical Switches?

Ex-proof electrical switches are an important part of electrical current interrupters or systems that allow the redirection of current from one conductor to another, designed to be used in potentially explosive environments. They are specially designed to prevent the ignition of flammable gases, vapors, or dust that may be present in the circuit.

Additionally, they are designed to meet strict safety standards such as ATEX and IECEx, which set guidelines for the use of electrical equipment in explosive environments.

In general, Ex-proof electrical switches are a critical component of many industrial systems because they help ensure the safety of workers and equipment operating in potentially hazardous environments.

Where Are Ex-proof Electrical Switches Used?

Ex-proof electrical switches are commonly used in industries such as oil and gas, chemical processing, and pharmaceutical manufacturing, where there is a risk of explosion due to the presence of flammable materials. They are also used in underground mines and other locations with a high risk of explosion.
