Abstract
The utility model provides an electrical auxiliary switch which comprises a closed switch housing formed by a housing body and a cover plate. A push bar is disposed in the switch housing. One end of the push bar extends out of the switch housing. The other end of the push bar is connected with one end of a large spring, and the other end of the large spring is abutted to the bottom of the housing body. A plurality of connecting pins are arranged on the housing body. A fixed contact of each connecting pin is located in the housing body. A reed switch is connected between the fixed contacts of one pair of connecting pins. A magnet is mounted in the push bar. When the push bar is pushed or released to reset, the magnet approaches or leaves the reed switch to connect or disconnect the reed switch. A moving contact plate is further mounted on the push bar. When the push bar is pushed or released to reset, a contact of the moving contact plate contacts with or leaves the fixed contacts of the pair of connecting pins simultaneously. The electrical auxiliary switch has the advantages that a contact switch is combined with a magnetic switch, a sampling end operates in a vacuum state, and accordingly a computer is reliable in sampling, able to operate for 1000000 times, free of conditions such as poor contact, and adaptive to compatibility of strong and weak currents.
Description
Technical field
The utility model relates to a kind of electrical equipment auxiliary switch, specifically a kind of switch that can control the strong and weak electricity connecting and disconnecting of the circuit.
Background technology
Along with modern development, computer is constantly universal, and all trades and professions all adopt computer to manage production control, and old auxiliary switch can not adapt to existing development need.General auxiliary switch can only be used for large electric current high voltage.As be connected sampling with computer with this auxiliary switch, will cause contact ineffective after use a period of time, computer is got less than signal (the signal voltage low current of taking a sample because of computer is little) and is made the computer erroneous judgement, causes to stop production or accident.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of electrical equipment auxiliary switch is provided, and can be used for controlling reliably weak electrical loop.
The technical scheme that provides according to the utility model, described electrical equipment auxiliary switch, comprise that housing and cover plate consist of the enclosed switch shell, be equipped with in switch housing by bar, stretch out switch housing by one, bar, the other end connects an end of big spring, and the big spring other end withstands housing bottom, be provided with a plurality of wiring pins on housing, the fixed contact of each wiring pin is positioned at housing; It connects tongue tube between the fixed contact of a pair of wiring pin, magnet is housed in by bar, when being pressed by bar or unclamping when resetting, described magnet near or leave tongue tube, cause reed switch conduction or disconnection.
Further, described by movable contact spring also is housed on bar, when being pressed by bar or unclamping when resetting, the contact on described movable contact spring contacts or leaves the fixed contact of a pair of wiring pin simultaneously.
Described by being provided with location notch in bar, described magnet is arranged in location notch.
Also be provided with compressed little spring in described location notch, be used for withstanding fixed magnet.
The utility model has the advantages that: this Novel assistant switch adopts contact switch to be combined with magnetic switch, the sampling end is operated in vacuum state, makes the computer sampling reliable, and the life-span reaches 1,000,000 times, there are not the situations such as loose contact, thoroughly make switch can adapt to the strong and weak electricity compatibility.Its generation makes vacuum contactor enter brand-new computer and controls the epoch.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 1, shown in 2, the utility model comprises: housing 1 and cover plate 2 consist of the enclosed switch shell, be equipped with in switch housing by bar 3, stretch out switch housing by 3 one, bar, the other end connects an end of big spring 7, and big spring 7 other ends withstand housing 1 bottom, be provided with a plurality of wiring pins 5 on housing 1, the fixed contact of each wiring pin 5 is positioned at housing 1.
The present embodiment comprise 4 the docking stitches 5, wherein have two the docking stitches 5 fixed contact between connect respectively a tongue tube 8.Be provided with the interior installation magnet 9 of 10, one location notchs 10 of location notch in by bar 3, the interior installation movable contact spring 4 of another location notch 10.Also be provided with compressed little spring 6 in location notch 10, be used for withstanding fixed magnet 9 and movable contact spring 4.When being pressed by bar 3 or unclamping when resetting, drive described magnet 9 near or leave tongue tube 8, cause tongue tube 8 conductings or disconnection; And drive the fixed contact that contact on described movable contact spring 4 contacted or left a pair of wiring pin 5 simultaneously.
Can assemble as required: two open and two close, three open and one close, three close one and open.
As Fig. 3, shown in 4, be one group of forceful electric power normal-closed end a-b, one group of forceful electric power Chang Kaiduan c-d, two groups of light current end e-g and f-h are applicable to computer sampling end.A-b and c-d are controlled by movable contact spring 4 and are switched on or switched off, and e-g and f-h are controlled by magnet 9 and tongue tube 8 and be switched on or switched off.
Can see, the utility model presses principle by bar 3 and spring reset by external force, and band moving magnet 9 and movable contact spring 4 are realized being switched on or switched off the electric loop of controlling, and has both gone for the forceful electric power loop, again applicable to weak electrical loop.Ease of assembly, reliable operation.
