Born for extreme corrosive environment such as strong acid, strong alkaline, electrostatic discharging areas, SW-B series explosion proof switch is a special presence and usage to replace other traditional metal material of explosion proof light switch. Application for low temperature rise electrical material for components and increased safety glass fiber reinforced polyester housing, this model can be used as zone 2 light switch, division 2 for switch and anti spark power switch.

As a common used explosion proof switch, SW-A series explosion proof light switch is protected by flame proof aluminum housing to turn on and off the explosion proof lighting. Designed with on and off position for easy handling, this flame proof on and off switch directly connect and disconnect one or certain numbers of explosion proof lighting in planned areas with electrical power to realizing the illumination when necessary. Hazard class division can be class 1 switch, zone 1 in hazardous location.
