选配装接有水压开关至主控板时此功能有效。
Matching fitted pressure switch has access to the main control board when this function effectively.
低压或高压开关- - -用于当水压降低到预先设置的最低值或超过预先设置的最高值时,切断控制电流。
Low or high pressure switch - turns off control circuit when water pressure drops below a set minimum, or above a set maximum.
本实用新型结构简单,开关动作与水压无关,因此适用于各种不同水压的场所使用。
The on-off action of the utility model is irrelevant to the water pressure. Therefore, the utility model is suitable for being used in various places with different water pressures.
