Protected by flame proof housing or increased safety electrical parts, explosion proof switch is a common usage for end-to-end control unit to control the power on and off for explosion proof lighting whose low current is normally not more than 32 ampere in hazardous location. The housing of explosion proof light switch ranges from die cast aluminum alloy for most case and glass reinforced plastic for extreme corrosive case. No matter it shapes like on-off switch or button, explosion proof switch is a small size switch playing the same functions in real applications, you should select explosion proof panel if you intend to control the high current electrical equipment such as motor starter whose working current can be more than 32 ampere.
