Contact blade at one end by a bolt mounted touch base (or conductive rod). Touch to rotate the contact knife, and the other end connected to the stationary contact blade can be divided into the Department, and by the spring contact blade contact pressure at both ends to maintain. High voltage switches FN5-12 / 630A environmental conditions 1, altitude over 1000 meters; 2, ambient air temperature not higher than + 40 ℃ and no less than -10 ℃. 3 indoor spaces, the air relative humidity less than 90% (when the temperature is + 25 ℃); 4, non-conductive dust environment; 5, no damage to the metal and dielectric objects of corrosive gases; 6, no severe Local vibration and shock; 7, no fire and explosion hazard environments.
