Honeywell HONEYWELL Explosion-Proof Switch Application Range Explosion-proof switches are used in a variety of applications that require a safe, reliable, and easily disconnected connection. Especially in the manufacturing equipment and system power supply where explosive gas may exist; also used in the petrochemical industry; including mills, granaries, paint or ink manufacturers, wood processing plants, cement plants, shipping and sewage treatment. HONEYWELL explosion-proof switches are also suitable for use in external electrical equipment such as motors, pumps, lighting equipment, process control devices used in hazardous manufacturers and factories, or in explosive atmospheres that cause flammable gases, steam, mist or flammable dust.
