Both the KST temperature control switch and the KSD temperature control switch are mechanical temperature control switches, and the internal bimetal is used as the temperature sensing element to control the on and off of the circuit to protect the equipment. So what is the difference between the two?
The KSD series temperature control switch adopts butterfly-shaped bimetallic strip. When the equipment is working normally, the temperature switch is in a free state and does not have any action. When the equipment fails and generates high temperature, the bimetallic strip closes/opens, and when the normal temperature drops to Safe, bimetallic open/close. Used in household appliances, automotive diesel filter heating, disinfection cabinets, electric welding machines, etc.
The KST series temperature control switch is an adjustable temperature control switch. There are flashing, slow action and other types. The working principle is also to use the thermal characteristics of the bimetallic sheet. When the temperature control switch is heated or cooled, it will move and produce Mechanical energy pushes the energy storage reed, but the thermal and cold displacement of the bimetal does not act on the contact immediately, but when the energy storage reed slowly accumulates to the turning point, it makes a sudden action, and the contact is quickly clutched to make and break. When opening the circuit and adjusting the temperature, the KST thermostat has a wide range of applications and can be used in more temperature adjustment and control appliances. Generally used in electric irons, high and low switch cabinets, etc., rail type, easy to install.
