2.Construction
Explosion-proof limit switch consists of explosion-proof connection head, explosion-proof micro-switch, contacting wheel guide rod and rotating device etc. it is divided into the following types according to the structure:1. Single-wheel type 2. direct-contacting type3. v forked type4. telescopic rod type 5.rod type
types as follows upon the function：
1. Sole-switch 2. Dual-switch 3. completely opening or closing types by leftward and rightward roating, all are able to auto matically reset.
The explosion-proof limit switch holds not only good explosion-proof property but also water-proof, dust and corrosion resisting etc.advantages. |
and the driving rod can still go on rotating by about 36
