Abstract
The utility model relates to a mechanical pressing switch. The outer part of a push rod with a button is provided with a restoring spring. One end of the spring supports a casing. The end of the push rod is provided with a small circular hole. One end of a copper rear hook falls into the small circular hole, and the other end falls into a peach-shaped track in a peach-shaped block. The copper rear hook can do one-way movement inside the track. The concave pit in the lower edge of the peach-shaped track is provided with a dipolar contact piece which is conducted through a copper pulling hook. The peach-shaped block is fixed on the casing. The mechanical pressing switch has the characteristics of simple structure, good contact performance and aging resistance.
Description
The utility model relates to a kind of mechanical switch, particularly a kind of push switch.
The existing mechanical switch.Approximately be divided into two kinds of swing type and push types, push switch is mainly by button, and conductor push rod and the two poles of the earth contact are formed, and is moving of movable contact spring by the conductor push rod, touches the two poles of the earth static contact simultaneously and conducting, otherwise promptly disconnects, and this switch has the shortcoming of loose contact.
The purpose of this utility model is to design a kind of good push switch that contacts.
Task of the present utility model is finished like this, the push rod of band button is with a back-moving spring outward, one end of spring withstands on the shell, the push rod end offers a small sircle hole, and an end of copper pull hook falls in the hole, and the other end falls in the peach shape track of peach shape piece, the copper pull hook can be done unidirectional moving in orbit, the lower edge pit of peach shape track is provided with the two poles of the earth contact, makes its conducting by the copper pull hook, and peach shape piece is fixed on the shell.Press the button, push rod drive the copper pull hook along a side shifting of peach shape track to track lower edge pit, the copper pull hook catches on the two poles of the earth contact, i.e. switch closure under the effect of back-moving spring power; Pressing button again, the copper pull hook leaves the lower edge pit, and the opposite side track resets in the action of reset spring lower edge, and this moment, switch disconnected.
The utlity model has simple in structurely, contact is good, ageing-resistant characteristics.
Below in conjunction with legend the utility model is described further;
Accompanying drawing is the push switch schematic diagram
With reference to accompanying drawing, but button 1 and push rod 3 disjunctor single injection-moldeds, peach shape piece 8 and shell 4 all can adopt plastic part, the push rod 3 outer back-moving springs 2 that are with, one end of spring 2 withstands on the shell 4, push rod 3 ends offer small sircle hole 5, one end of copper pull hook 6 falls in the circular hole 5 and is fixed on push rod 3 ends by elastic tape 7, offer peach shape track 9 on the peach shape piece 8, pit is provided with the two poles of the earth contact 10 in the lower edge of track 9, and the other end of copper pull hook 6 falls in the peach shape track 9, can do unidirectional moving in orbit, when moving to the lower edge pit of track 9, connect the two poles of the earth contact.Peach shape piece 8 is provided with two binding posts 11, joins with the two poles of the earth contact 10 respectively.Peach shape piece 8 is fixed on the shell 4.
Claims (2)
1, a kind of push switch, it is characterized in that being with a back-moving spring outward with the push rod of button, one end of spring withstands on the shell, the push rod end offers a small sircle hole, and an end of copper pull hook falls in the hole, and the other end falls in the peach shape track of peach shape piece, the copper pull hook can be done unidirectional moving in orbit, the lower edge pit of peach shape track is provided with the two poles of the earth contact, makes its conducting by the copper pull hook, and peach shape piece is fixed on the shell.
