The KW3A micro switch is a basic switch that can be used in wide range of appliances like home appliances, automobiles and etc. It has a wide temperature range, up to 200°C and as low as -10°C, and can be used in a variety of places. Maintains switch stability even in harsh environments. DONGNAN Switch can provide high quality switches and fast delivery. KW3A micro switches are produced using automated machines, which can detect each switch in each process to ensure the quality of the switch. It also speeds up order delivery to a certain extent.
