Abstract

A switch with a good hand feeling comprising a top cover (1), a base (2), a fixed terminal (3), a movable terminal (4) and a press piece (5). A guide post (21) is disposed on the base, and the press piece is installed on the guide post with a reset spring (8) sleeved thereon. The top cover of the upper end of the press piece is exposed to be pressed. A cavity is formed by buckling the top cover and the base. The fixed terminal and the movable terminal are disposed on a side of the press piece in the cavity. One end of the fixed terminal and one end of the movable terminal both extend out of the base to connect to an external circuit. An upward and downward movement of the press piece drives the movable terminal to move, so as to control the connection and disconnection between the movable terminal and the fixed terminal. A tactile dome (6) is disposed on the other side of the press piece, and protruding ribs (53) are disposed on a corresponding side surface of the press piece. The upward and downward movement of the press piece drives the movable terminal to move, so that the protruding ribs press the dome to improve the pressing touch. The switch further comprises a key indicator (7) disposed on the base. By adding the tactile dome inside the switch, the switch has a good hand feeling. In addition, the switch has a simple structure, and lasts longer.

使用时，当按压件5被按压时，按压件5的定位杆顺着底座2的导柱导孔往下运动，复位弹簧被挤压，按压件5的凸起51坡面会贴着可动端子4的接触部42往下移动，接触部42因为失去按压件5凸起51所支撑的力，通过金属片弯折后所产生的弹力往前运动，最后与固定端子3接触，分别连接在可动端子4与固定端子3的电路导通，产生一个信号；同时按压件5通过凸愣52挤压触感弹片6，使操作者有明显的按压触感。当按压件5按压后去掉按压的力时，因为复位弹簧的回位弹力，在按压件5上施加一个往上的力，这时按压件5凸起51也会往上推起，因为坡面的作用，会将可动端子4的接触部42往后推开，此时可动端子4与固定端子3会断开接触，恢复到按压前的位置。本实施例中所述开关也设于指示灯7。 In use, when the pressing member 5 is pressed, the positioning rod of the pressing member 5 moves downward along the guide post hole of the base 2, the return spring is pressed, and the slope of the protrusion 51 of the pressing member 5 is movable The contact portion 42 of the terminal 4 moves downward, and the contact portion 42 moves forward due to the force supported by the protrusion 51 of the pressing member 5, and the elastic force generated by the bending of the metal piece moves forward, and finally contacts the fixed terminal 3, and is respectively connected to The movable terminal 4 and the circuit of the fixed terminal 3 are electrically connected to generate a signal; at the same time, the pressing member 5 presses the touch elastic piece 6 through the tenon 52, so that the operator has a distinct pressing feeling. When the pressing force is removed and the pressing force is removed, an upward force is applied to the pressing member 5 due to the return spring force of the return spring, and the protrusion 51 of the pressing member 5 is also pushed up because of the slope surface. The action of the contact portion 42 of the movable terminal 4 is pushed back, and the movable terminal 4 and the fixed terminal 3 are disconnected from each other, and the position is restored to the position before the pressing. The switch in this embodiment is also provided on the indicator light 7.
