Currently used a kind of pressure switch, after it is subject to certain water pressure, just switches on power；When otherwise hydraulic pressure is less than predetermined value, just deenergization。It is provided with electric switch in heater circuit, is connected with insulation hydraulic pressure switch end, break-make water power, is inside provided with temperature controller and anti-dry burning device, also can be provided withEarth leakage circuit-breaker。Usually a kind of microswitch of the pressure switch of electric hot water tap, fine motionSwitchIt is that there is small contact separation and snap-action mechanism, by regulationStrokeCarry out switching action with the power of regulationContactMechanism, covers with shell, has a kind of switch of drive rod outside it。Existing microswitch, including button, input terminal and outlet terminal, circuit is made to connect during button press, otherwise circuit disconnects, but its volume of existing microswitch is bigger so that production cost increases, and when assembling, microswitch is inconvenient to install and wiring so that the range of fit of product is little。

Summary of the invention

This utility model is for solving microswitch wiring trouble, problem that wiring easily shifts, it is provided that the microswitch that a kind of wiring is novel simply and easily when assembling in background technology。

The technical solution of the utility model is: a kind of microswitch, including housing, button and binding post, described housing includes upper cover and base, described binding post includes the first binding post and the second binding post, it is characterized in that: in described base, be provided with back-moving spring, dynamic touch panel and jointed shaft, dynamic touch panel is arranged in housing by jointed shaft is hinged, dynamic touch panel one end is placed between button and back-moving spring, the stationary contact of the dynamic touch panel other end and the first binding post is correspondingly arranged, described base includes the long sidewall on length direction and the broad side walls on width, one end of described first binding post and the second binding post is placed in base intracavity, the other end all extends to outside base, being positioned on the outer one end of base and be respectively equipped with wiring hole of described first binding post and the second binding post, and the both sides being positioned at wiring hole are respectively arranged with draw-in groove。

By adopting such scheme, the setting of wiring hole, it is simple to the installation of inlet wire and outlet, it is provided with draw-in groove, it is to avoid inlet wire and the sliding after outlet installation, so that the mode of connection is more reliable, line conduction is more smooth and easy simultaneously。

Of the present utility model being arranged so that described second binding post and the first binding post entirety all become Z-shaped, described first binding post to pass setting from broad side walls further, described second binding post passes setting from long sidewall；Described first binding post and the second binding post are positioned at the both sides, end of base and each extend over and be provided with boss, and corresponding being provided with on upper cover and base coordinates with boss grafting and realize the first binding post and jack that the second binding post is fixed；Described first binding post and the second binding post are positioned at the part of base at least provided with two groups of boss, and corresponding jack also has at least two groups。

By adopting such scheme, it is the further restriction of pair of wire connection terminals structure, is so conducive to the convenience that product is installed, additionally makes interiors of products rational in infrastructure, what extend the service life of product, boss and jack and projection and slot is disposed to the binding post steadiness at chassis interior。

Below in conjunction with accompanying drawing, this utility model embodiment is described further。
