Mine-used intrinsic safety two-way emergency stop lock switch

Use environment:

The lockout switch should work normally under the following environmental conditions:

     a) Ambient temperature: 0℃～＋40℃;

     b) Average relative humidity: not more than 95% (+25℃);

     c) Atmospheric pressure: 80kPa～106kPa;

     d) Where there is no significant vibration and impact;

     e) There is an explosive mixture of methane and coal dust in the coal mine, but there is no mixture of corrosive gases that damage the insulation.

The worst storage and transportation conditions that the lock switch can withstand are:

     a) High temperature: +60℃;

     b) Low temperature: -40℃;

     c) Vibration: 50m/s2;

     d) Impact: 500m/s2.
