Abstract

A push-button switch capable of adjusting output power includes a housing. The housing includes a contact assembly and a power adjustment assembly therein. The contact assembly includes an upper terminal, a lower terminal and a connecting elastic plate below the upper terminal. A support seat is provided in the housing. An upper end of the support seat is provided with a first bracket. The first bracket is inserted through the connecting elastic plate. The first bracket is provided with a first slot. One end of the connecting elastic plate is fixedly connected to the upper terminal. Another end of the connecting elastic plate is engaged with the first slot. A drive mechanism is provided above the connecting elastic plate for driving the connecting elastic plate downward. The push-button switch has an ergonomic design.

First claim

What is claimed is:

1. A push-button switch capable of adjusting output power, comprising a housing ( 1 ), the housing ( 1 ) including a contact assembly and a power adjustment assembly therein, characterized by: the contact assembly including an upper terminal ( 3 ), a lower terminal ( 4 ) and a connecting elastic plate ( 5 ) below the upper terminal ( 3 ), a support seat ( 6 ) being provided in the housing ( 1 ), an upper end of the support seat ( 6 ) being provided with a first bracket ( 61 ), the first bracket ( 61 ) being inserted through the connecting elastic plate ( 5 ), the first bracket ( 61 ) being provided with a first slot ( 62 ), one end of the connecting elastic plate ( 5 ) being fixedly connected to the upper terminal ( 3 ), another end of the connecting elastic plate ( 5 ) being engaged with the first slot ( 62 ), a drive mechanism being provided above the connecting elastic plate ( 5 ) for driving the connecting elastic plate ( 5 ) downward,
wherein the drive mechanism includes a press block ( 71 ) for pressing the connecting elastic plate ( 5 ) downward, a push rod ( 72 ) for pushing the press block ( 71 ) downward, and a returning mechanism for returning the push rod ( 72 ).

2. The push-button switch capable of adjusting output power as claimed in claim 1 , wherein the press block ( 71 ) includes a press portion for pressing the connecting elastic plate ( 5 ) and a connecting portion for driving the push rod ( 72 ), and a lower end of the push rod ( 72 ) is provided with a push block ( 721 ) for pushing the press block ( 71 ) downward.

3. The push-button switch capable of adjusting output power as claimed in claim 2 , wherein the connecting portion of the press block ( 71 ) has a contact curved surface, the push block ( 721 ) has an engaging bevel, and the engaging bevel leans against the contact curved surface.

4. The push-button switch capable of adjusting output power as claimed in claim 1 , wherein the returning mechanism includes a spring ( 73 ), one end of the spring ( 73 ) leans against the push rod ( 72 ), and another end of the spring ( 73 ) leans against an inner wall of the housing ( 1 ).

5. The push-button switch capable of adjusting output power as claimed in claim 1 , wherein the drive mechanism includes an auxiliary returning mechanism, the auxiliary returning mechanism includes a returning elastic piece ( 74 ), the connecting elastic plate ( 5 ) has a first receiving slot ( 51 ), the returning elastic piece ( 74 ) is disposed in the first receiving slot ( 51 ), the upper end of the support seat ( 6 ) is provided with a second bracket ( 63 ), the second bracket ( 63 ) is inserted through the connecting elastic plate ( 5 ), the second bracket ( 63 ) is provided with a second slot ( 64 ), one end of the returning elastic piece ( 74 ) is connected with the connecting elastic plate ( 5 ), and another end of the returning elastic piece ( 74 ) is engaged with the second slot ( 64 ).

6. The push-button switch capable of adjusting output power as claimed in claim 1 , wherein the power adjustment assembly includes a circuit board ( 81 ) and a slider ( 82 ) in contact with the circuit board ( 81 ), an upper end of the push rod ( 72 ) is provided with a second receiving slot, the slider ( 82 ) includes a fixed portion and a contact portion, the fixed portion of the slider ( 82 ) is disposed in the second receiving slot, and the contact portion of the slider ( 82 ) is in contact with the circuit board ( 81 ).
