Microswitch assembly and valve

The invention provides a microswitch assembly and a valve. The microswitch assembly comprises a microswitch which comprises a full-open circuit and a full-closed circuit. A limiting groove is formed in the outer periphery of the rotating part; the elastic piece is provided with a contact switch; the elastic piece comprises a first elastic piece body and a second elastic piece body, and the first elastic piece body and the second elastic piece body abut against the outer periphery of the rotating piece in a spaced mode. According to the valve actuator, the rotating piece is combined with the elastic piece to achieve opening or closing of the microswitch, the overall structure is small, and the size of the valve actuator is reduced. 本申请提供一种微动开关组件和阀门。该微动开关组件包括微动开关，包括有全开电路和全关电路；转动件，外周缘上设有限位槽；弹性件，设有触点开关；所述弹性件包括有：第一弹性件和第二弹性件，且所述第一弹性件和所述第二弹性件间隔地抵接于所述转动件的外周缘上。本申请采用转动件结合弹性件来实现微动开关的打开或关闭，整体结构小，减小了阀门执行器的体积。
