KJT stainless steel travel switch is a fully enclosed contact switch made of stainless steel material. One group is normally open and one group is normally closed. The maximum allowable current is 5A/AC 220V (other voltages are subject to reservation). The contacts can be used at high temperatures after special treatment. It can be used for a long time in the environment without being damaged by oxidation or pollution.
KJT-XW series stainless steel travel switches have a maximum temperature of 350°C and can be divided into more than ten specifications such as roller arm type, adjustable rod type, pressure plunger type and roller pressure column type, which can meet the requirements of different occasions. Widely used in electric power, chemical industry, petroleum, textile, steel and other industries.
