A variation in the commonly used one-way switch, this product has instilled the rocker mechanism. It also works on other mandates like??the IP 20 protection, finger-proof, and tunnel terminals. All this is carried out to ensure complete protection from unwanted and??unwarranted accidents like sudden visibility of sparks or sudden onset fire. A one-way switch with an indicator comes in a pack of 20 pieces. The spring used in this switch is made from EN-42 material, again to maintain complete security.
