Abstract

PURPOSE: To enable a pump to be operated easier and to be manufactured in a small size, by linking a pressure switch through a flexible pipe, and by making it possible to slide while maintaining the linkage and removing the pressure switch.
CONSTITUTION: In the case of removing a switch cover 16 for adjustment of a pressure switch 12, etc., it can be done simply by removing a supporting body 10 from a pump base 2, and since linkage between the pressure switch 12 and inside of a pump 6 is maintained by a small flexible pipe 20 at that time, pressurized water in the pump 6 can be prevented from jetting out and the pressure switch 12 can be adjusted while the pump is in operation, and therefore, it can be maintained better. And, as the pressure switch 12 is designed capable not only of being arranged in an appropriate position according to structure of the pump but also of being arranged in a narrow room at the bottom of a pressure tank 8, the pump as whole becomes able to be manufactured in a small size.
