Abstract

The utility model relates to a change-over switch comprising a handle, a handle jaw, a rotating shaft, an indication board, a panel of the indication board, an installing panel, a positioning system, a stop system, a contact system, a bottom cover and a fastener, wherein the handle jaw is embedded in the handle, the rotating shaft is tightly held by the handle jaw, the indication board is installed on the panel of the indication board, and the rotating shaft sequentially penetrates through the panel of the indication board, the installing panel, the positioning system and the contact system and is connected to form a whole by the fastener after the bottom cover is additionally covered; the rotating shaft is made of metal; the movement of the change-over switch is controlled by the metal rotating shaft, cams and the metal rotating shaft adopt tight fit, and the synchronous movement of a plurality of layers of cams is realized, so that the change-over synchronization property of each contact is enhanced; meanwhile, the metal rotating shaft is not easy to soften under a high-temperature environment and also is not easy to be in brittle fracture under a low-temperature environment, thereby enhancing the service life of the change-over switch; and meanwhile, the application field of the change-over switch is widened, thereby overcoming the defect that a plastic part used in a traditional product is easy to damage.

Description

Change over switch

Technical field

The utility model belongs to the change over switch field, is applicable to mechanical switch.

Background technology

The switch mechanical part all adopts plastic material both at home and abroad at present, interlock continuously after the machine-shaping, and there is accumulated error in this compound mode, cause each contact action consistency of switch poor, and plastic material is easily aging in time, easily softening in hot environment, the easy brittle failure of low temperature environment has limited the scope of application.

Summary of the invention

For solving the defective that prior art exists, provide a kind of change over switch.

The utility model is a kind of change over switch, comprise handle, handle pawl, metal rotating shaft, direction board, direction board panel, installation panel, navigation system, caging system, contact system, end cover and securing member, wherein handle is embedded in the handle pawl, be equipped with metal rotating shaft in the handle pawl, direction board is installed on the direction board panel, direction board panel, installation panel, navigation system, caging system, contact system are passed in rotating shaft in proper order, add a cover cover back, the end and connect into as a whole by securing member.

Further, the described metal rotating shaft of this change over switch is made by copper, iron or aluminium, adopt square axis or six square shafts, be positioned at this change over switch geometric center, processing technology has high requirements to the metal rotating shaft glacing flatness, can rotate synchronously at rotation process shaft each several part, and metal rotating shaft drives cam control contact action, thereby make contact action synchronism height, switch performance is reliable.Metal rotating shaft is difficult for softening under hot environment simultaneously, is difficult for brittle failure under low temperature environment, thereby has improved the useful life of change over switch, has widened the application of change over switch, and has overcome the defective of using plastic part to damage easily in the existing product.

Further, the described caging system of this change over switch is made up of banking stop, locating part and spacer pin, locating part is enclosed within on the metal rotating shaft, perforate on the banking stop can be carried out

circumference

4 or 6 or 8 or 12 or 16 or 18 or 20 five equilibriums, thereby by spacer pin being inserted the restriction metal rotating shaft anglec of rotation in the different holes, realize multiple spacing angle, form limit effect, having overcome in the past every kind of spacing angle all needs the situation that realizes with specific part, saves cost and memory space.
