スイツチ。[Claims for Utility Model Registration] 1. Proximity in which the flow path of the fluid is constricted and then the fluid is ejected from the ejection port, and when an object comes close to the ejection port, the presence of an object is detected by utilizing the pressure fluctuation of the ejected fluid. In the switch, there is an element that converts the pressure value of the ejected fluid into an amount of electricity, and this amount of electricity is calculated.
A proximity switch having a circuit that generates an electrical signal when a preset condition is met. 2. A utility model registration claim set forth in paragraph 1 consisting of a device that throttles a fluid flow path and a structure in which fluid is introduced from two locations sandwiching this device to an element that converts the pressure value of the fluid into an electrical quantity. Proximity switch. 3. The proximity switch according to claim 1, which is a registered utility model and is provided with a thin tube that is flexible and can stand on its own, connecting a structure that converts a pressure value into an amount of electricity and a jet nozzle.
