We are a switch manufacturer. The company takes market development and technology development as the forerunner. It is specialized in the production, processing, distribution and wholesale of various switches, travel switches, micro switches, foot switches, toggle switches, and boat switches. species series. The company operates in strict accordance with the manufacturing standards. Over the years, we have cultivated a professional manufacturing team: we have more than 20 years of manufacturing experience: to provide users with safe and reliable quality products. The product is well received by users in the process of making. We have established long-term cooperative relations with many enterprises with strong strength, reasonable price and excellent service. The company adheres to the business tenet of “honesty, customer first, reputation”,

(1) Structure and working principle

The outer casing of the limit switch is made of copper alloy, and its shell has good mechanical strength and good corrosion resistance. Under the environmental conditions of marine ships, the performance of the material will not deteriorate, the outer casing type is protective, and the protection level can reach IP67. The mechanical structure of the limit switch is to push the switch contact through the push rod or swing arm to complete the required function. The contact opening and closing of the limit switch is completed by the rotation of the concave shaft. Due to the action of the spring, the switch can be automatically reset. The operating position angle is 85°+0°-85°, and the contact closing and opening action angles are not greater than 30°, and can be used without damage in 360° rotation.

(2) Current and voltage parameters

The limit switch stipulates that the heating current is 16A; the rated insulation voltage is 500V, the rated working voltage for directly controlling the 5.5Kw three-phase asynchronous motor is below 440V, and the rated working current is 12A. The limit switch is used in AC and DC 500V circuits to limit the stroke of various mechanisms. Stainless steel material, mechanical rotating parts are wear-resistant materials. The switch’s seals are resistant to oil contamination and longevity.

(3) Purpose:

This product is a limit switch suitable for ships, offshore platforms, ports and other mechanical equipment that can limit the travel in the control circuit of electrical equipment. It has the advantages of reasonable and reliable mechanical structure, small size, beautiful appearance, and convenient installation. Use in all climates. The shell of this product is made of alloy or stainless steel, which has good mechanical strength and corrosion resistance, and the protection level is IP67 or above.

(4) Use environment

The altitude does not exceed 2000 meters. The ambient air temperature is not higher than +40°C, not lower than -5°°C, the average temperature within 24 hours does not exceed +35°C, the air at the installation site is clean, and the maximum relative humidity of the atmosphere is 40°C. The average maximum relative humidity is 90% when the average temperature of the wet month is 25°C, and the condensation on the surface of the product due to temperature changes is considered.
