Claims (1)

[Scope of Claim for Utility Model Registration] 1. A push button having a head and a shaft extending from the head, a reciprocating valve attached to the tip of the shaft so as to be able to slide freely while being biased in the same direction as the pushing direction of the push button; A first flow port and a second flow port are provided to face each other with a reciprocating valve in between, and the push button is held so that its shaft portion can be freely slid in the axial direction and is urged outward so that the reciprocating valve It consists of a plug body that is attached by blocking the first flow port, an engaging member is attached to the push button side, and a guide path for guiding the engaging member is provided on the plug body side, and the push button is inserted into the guide path. When you release your hand after pushing it a certain amount, the engaging member engages and holds the push button in the pressed state, and when you release your hand after pushing the push button a little further from the pressed state, A flow path switching plug, comprising an engaging portion that releases the engagement and returns the push button to the protruding state. 2. The guide path is continuous with a base path in which the engaging member is positioned when the push button is in an extended state, and is continuous with the base path, and when the push button is pushed in, the engaging member enters from the base path to position the engaging portion. an outgoing path in which the push button moves past the push button; Then, when the push button is pushed a little again, the engagement member disengages from the engagement portion and enters through the engagement path, and then when the push button is released again, the engagement member passes through. The flow path switching plug according to claim 1, further comprising: a return path that returns to the base path; 3. The flow path switching plug according to claim 2, wherein abutment portions are provided at the end of the forward path and at the beginning of the return path, respectively, with which the engaging member abuts and prevents further pushing of the push button. 4 Press the tip of the engaging member against the bottom surface of the guide path by urging the engaging member or using the elasticity of the engaging member itself, and at the same time, press the tip of the engaging member against the bottom surface of the guide path, and also press the tip of the engaging member against the bottom surface of the guide path, and also press the tip of the engaging member against the bottom surface of the guide path, and 4. The flow path switching plug according to claim 3, further comprising a stepped portion for preventing the engaging member from returning, between the return path and the base path. 5 Operate the push button to open either the first flow port or the second flow port, and selectively switch the liquid from one flow path to either one of the two flow paths to flow out. The flow path switching plug according to claim 1. 6. The flow path switching faucet according to claim 5, wherein the first flow port communicates with a faucet or a shower port, and the second flow port communicates with a shower port or a faucet. 7 Operate the push button to open either the first flow port or the second flow port, switch to either one of the two channels as appropriate, and selectively drain the liquid from one of the channels into one channel. The flow path switching plug according to claim 1, wherein the flow path switching plug is made of:
