A microswitch, which comprises a housing (1); a contact component (2), an input element (3), and an output component (4) are provided inside the housing (1); the contact component (2) and the input element (3) are constantly connected; a press element (5) that controls the connection or disconnection of the contact component (2) and the output component (4) is provided on the housing (1); a circuit board (6) is provided inside the housing (1); the output component (4) comprises a first output pin (412) and a second output pin (422) on the circuit board (6); the circuit board (6) is electrically connected to the input element (3), the first output pin (412), and the second output pin (422); the circuit board (6) is provided with a first resistor (8) and a second resistor (9); the circuit board (6) is provided with two connecting lines (10) that respectively input and output current; the output component (4) comprises a first output element (411) and a second output element (421); the contact component (2) is constantly connected to the first output element (411) or the second output element (421); and a switch component (7) that connects the first output pin (412) and the first output element (411) or the second output pin (422) and the second output element (421) is provided inside the housing (1). By controlling the press element (5) and the switch component (7) on a switch, three-gear changes of the current output are achieved, leading to more application ideas for the microswitch.

A protective switch of a pressure cooker lid, relating to the field of switches. The protective switch comprises a shell (1). A push rod (2) is slidably connected to the shell (1). The end of the push rod (2) exceeding the shell (1) is fixedly connected to a water diversion part (36). A reset spring (3) for driving the push rod (2) to reset is provided in the shell (1). A moving contact member (5) is provided on the push rod (2). A static contact member (6) is provided in the shell (1). The static contact member (6) is electrically connected to a wiring terminal (24). The moving contact member (5) comprises an insert plate (7) relatively and fixedly connected to the push rod (2), a copper body (8) provided on the insert plate (7), and copper contact piece sets (9) fixedly connected to the copper body (8). The static contact member (6) comprises a stabilizing plate (17) provided in the shell (1) and copper abutting pieces (18) fixedly arranged on the stabilizing plate (17). The copper abutting pieces (18) are electrically connected to a connecting terminal. There are two copper abutting pieces (18) and two copper contact piece sets (9) which have one-to-one correspondence. The copper contact piece sets (9) can deform and are in contact with the copper abutting pieces (18) to achieve connection or disconnection between the two copper abutting pieces (18). The protective switch of the pressure cooker lid replaces silver point contact with the mode that the copper members are in contact with each other, and has the effect of reducing cost.
