Abstract
The invention relates to a change-over switch which comprises a shell body, an operating mechanism, a contact terminal system, and a hand shank and the like. The change-over switch is simple, practical and low in cost, and can be applied to circuits with alternating power lower than 380v 10 kw to directly be switched on an asynchronous motor which is enabled to be started, operated, stopped and run in the inverted direction. The change-over switch overcomes the defect of an existing product. A temperature control device is added. Various accidents caused by overload, over current and scorification or other reasons can be avoided and reduced.
Description
One, technical field
The present invention relates to a kind of switch, relate in particular to a kind of two-direction switch.
Two, background technology
Switch is a kind of electrical equipment of commonly using, and its safe handling is particularly important, and two-direction switch in use has the defectives such as overload, overcurrent, scorification at present, easily causes various accidents.
Three, summary of the invention
In order to overcome the deficiencies in the prior art and defective, the invention provides a kind of two-direction switch, the present invention can prevent effectively because a variety of causes transships, overcurrent, scorification and the accident that occurs.
The object of the present invention is achieved like this:
Two-direction switch of the present invention is comprised of housing, operating mechanism, contact system, handle etc., it is characterized in that being equipped with on the contact splicing ear attemperating unit, and warning device is housed on the housing.It is characterized in that attemperating unit can be thermostat, temperature switch, thermal protector, thermistor.The temperature-control range that it is characterized in that attemperating unit can be set early warning temperature and break-off signal according to protection range.It is characterized in that attemperating unit can be one two or N.
Advantage of the present invention is as follows:
Two-direction switch of the present invention, simple, practical, cost is low, it goes for exchanging directly connects asynchronous motor in the following circuit of 10kw, make its startup, turn round, stop,, reach inverted running.It has overcome the deficiency of existing product, has increased attemperating unit, it can avoid and reduce because of the overload that a variety of causes causes, overcurrent, scorification cause various accidents.
Four, description of drawings
The present invention will be further described below in conjunction with drawings and Examples
Fig. 1 is two-direction switch embodiment schematic diagram of the present invention
1. two-direction switchs among the figure, 2. splicing ear, 3. attemperating unit, 4. warning device 5. housings.
Five, embodiment
Comprise housing, operating mechanism, contact system, handle etc. in the two-direction switch (1) in the drawings, have splicing ear (2) to be embedded with attemperating unit (3) on it in the housing (5), warning device (4) is arranged on the housing (5).
Claims (4)
1. two-direction switch, it is comprised of housing, operating mechanism, contact system, handle etc., it is characterized in that being embedded with on the contact splicing ear attemperating unit, and warning device is housed on the housing.
2. two-direction switch as claimed in claim 1 is characterized in that the temperature-control range of attemperating unit can be set early warning temperature and break-off signal according to protection range.
3. two-direction switch as claimed in claim 1 is characterized in that attemperating unit can be one two or N.
4. two-direction switch as claimed in claim 1 is characterized in that attemperating unit can be thermostat, temperature switch, thermal protector, thermistor.
