Features: The COB series are used in controlling circuits of AC 50HZ or 60HZ, Voltage to 660V, and DC voltage below 400v, it is used for controlling signal and interlocking. The main body adopts zinc alloy and high-grade anti-flaming plastic, the contact adopts a circuit of AC voltage 380v, 50hz, or 60hz, and DC voltage below 380V. Used as kinds of indication signals, warning signals, accident signals, and other signals. These are rainproof crane control push button switch which is newly developed products. These are made up of very high-quality fine plastic, and their design is very beautiful. These have advanced and big contact capacity, and mechanical interlocking, and if necessary they can achieve interlock circuits to assure more safety and reliable use. The product-matched cable jacket and waterproof rubber sealing strip, have a good (IP65 level) performance in dust and rain. So these are most suitable for the remote control in outdoor, rainy and snowy, dusty, and damp environments, such as electric hoists, open conveyor belts, building lines, etc. Specifications: Model: COB-65 Material: Plastic Waterproof: yes Color: Orange.
