Specific embodiment
In order to facilitate the understanding of those skilled in the art, below in conjunction with attached drawing and embodiment to the utility model carry out into
One step detailed description.
Embodiment one
Refering to fig. 1 ~ 5,7 ~ 9, a kind of microswitch, also referred to as microswitch.Microswitch include shell 1, mounting base 2,
Resistance 3 and multiple terminals 4, shell 1 fixes and supports structure as switch entirety, generally using insulating materials such as plastic cement.Peace
Dress seat 2 is used to install each terminal 4, clamping structure can be arranged in mounting base 2, and terminal 4 is fixed in mounting base 2,
It can be locked using screw.Mounting base 2 is also isolation material, and mounting base 2 itself generally fixes in shell 1, and shell 1 can be set
Two parts are set to, and two parts are fixed together by screw or buckle structure, internal mounting base 2 can be clamped when fixed solid
It is fixed.Each terminal 4 reaches outside shell 1 from shell 1, convenient to be electrically connected with external circuit.Resistance 3 is welded on terminal 4
Between, so as to which resistance 3 is linked into circuit by terminal 4, change the electrical property of circuit.
Refering to Fig. 3 ~ 5, limited position mechanism 41 is set, the resistance 3 passes through the limit peace of position-limit mechanism 41 on the terminal 4
Resistance can be limited to by dress, the position-limit mechanism 41 by the way of the resistance installation position periphery setting blocking column on terminal 4
On installation position, as position-limit mechanism 41 electricity can also be limited by setting one circle bulge-structure in resistance installation position periphery on terminal 4
The installation site of resistance.Position-limit mechanism is set resistance is mounted, high temperature, the vibration that can prevent resistance from being welded etc. are different on terminal
It is subjected to displacement when often, resistive displacement is avoided to can also be improved the yield of production to the influence of the appearance and service performance of product.?
After resistance 3 and terminal 4 are welded and fixed, the junction of the resistance 3 and terminal 4 coats one layer of covered plastics layer 9.Resistance passes through welding etc.
Mode is fixed on terminal, then carry out it is plastic, avoid resistance vibrated or temperature influence fall off or contact it is unreliable so that
Product is more reliable.
Refering to Fig. 3 and Fig. 5, preferably, the position-limit mechanism 41 in the present embodiment is opened using the limit being provided on terminal 4
Slot, the limit fluting is adapted with 3 shape of resistance, so as to limit to resistance 3.The system by the way of limit fluting
Make it is simple and convenient, directly slot, it is possible to reduce production cost.
Refering to Fig. 8 and Fig. 9, two terminals 4 can be set, a resistance 3 is connected between two terminals 4, thus by resistance 3
Access the electrical property that circuit changes circuit.The mode in Fig. 8 or Fig. 9 can be selected according to the pitch requirements between terminal 4.
Refering to three terminals 4 are respectively provided in Fig. 3 ~ 5,7, Fig. 3 ~ 5,7, connect respectively between one of terminal and another two terminal
Connecing a resistance 3, when use, which can choose, accesses circuit for any two terminal, so that the resistance in access circuit is different, it is right
The influence of circuit electrical property is also different.It is preferred that the resistance value of two resistance two resistance 3 is different, so that switch is in a manner of three kinds
When accessing circuit, the resistance value that three kinds of modes access circuit is all different, and influences also difference to the electrical of circuit.It in addition can also root
According to needing to be arranged four, five equal number of terminals, and pass through the difference of resistance connection type, realizes multiple resistance series connection, simultaneously
It arranges, go here and there and mix access circuit, realize the output of a variety of different resistance values.
It refering to fig. 1 and Fig. 2, further include button 6 and connection sheet 7, the button 6 is arranged on shell 1, and the button 6 drives
Dynamic connection sheet 7 is connected or disconnected with terminal 4.Connection sheet 7 is connect with terminal 4,3 short circuit of resistance that can will be connected on terminal 4,
Do not access circuit；Connection sheet 7 and terminal 4 are disconnected, resistance access circuit can be used.The connection sheet 7 can pass through bullet
Spring 8 is connected in mounting base 2, and the button 6 is crimped in connection sheet 7, and different functions is realized so as to push button 6.
Embodiment two
Refering to Fig. 6, a kind of microswitch of three terminals, the main structure of the microswitch is the same as example 1, no
It is the height that the position-limit mechanism 41 of the present embodiment does not use limit to slot, but uses resistance 3 be bonded between terminal 4 with place
Warm glue is subjected to displacement when being molded prevented also from resistance by high temperature and pressure as position-limit mechanism using high-temp glue fixed resistance 3,
