Features Stable performance: the sensor room and magnetic control room and electronic components room are separated, which can prevent the iron material in the pipe from being adsorbed by magnetic materials so as to avoid the failure of the switch. High temperature resistant: adopt high temperature materials, which can make sure the switch can bear hot and cold water. The highest resistant temperature is up to 70°C. The resetting spring adopts high quality material, which can be activated when the pressure of water flow reaches >0.03 KG, and the effect of low water pressure on the pump can be reached. Electronic components are used as the control devices to make the product no spark and completely enclosed in the work. Convenient to install, safe to use. The switch is used for small current devices such as laser, which are less than 110V. Description: It is widely applicable to increase water pressure in low water pressure area, especially for low water pressure of shower or automatic cycle of solar water heater.
