Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of push-button switch.
Background technology
Push-button switch utilizes button to promote transmission mechanism, makes moving contact and fixed contact drive the switch of realizing the circuit changing-over by on-off.Push-button switch is generally to adopt modular construction, by comprising button cap, back-moving spring, bridge contact and shell etc.The basic controlling such as push-button switch can be completed startup, stops, rotating, speed change and interlocking.But most push-button switch IP protection level in the market is low, the defective such as the poor and tightness of preventing dust water-based is poor.
a kind of button as disclosed in Chinese patent literature CN13344958A of the prior art, comprise upper casing, lower casing, volume film and mast, mast is through upper casing and lower casing, push-button switch is divided into upper casing part and lower casing part, it is planar that one end of mast is configured as the circular lid of action button, other end operating contact structure, the planar end of the circular lid of mast coordinates with the opening of upper casing, whole push-button switch is in sealing state, the volume film is arranged on mast on a large scale, be used for can inner, mast has together for fixedly holding the annular groove of rolling up film, one end of volume film and the annular groove on mast are connected, mast and volume film are made by two composition injection molding technologies, mast is different with the volume membrane material, and volume film and mast do not adhere to each other.Wherein, lower casing inside comprises main element, so the dustproof and waterproof sealing of lower casing inside is even more important.When mast moves in the service position, the planar end of the circular lid of mast leaves the opening of upper casing, the upper casing of push-button switch is inner to be connected with the push-button switch outside, at this moment, because volume film one end is connected with mast, the other end is positioned at the contact position of upper casing and lower casing, the volume film is divided into upper casing and lower casing two spaces that do not communicate with push-button switch inside, the inside that is the upper casing of push-button switch is communicated with push-button switch is outside, the inside of lower casing is not communicated with button is outside, therefore, by the volume film is set, guaranteed to a certain extent the dustproof and waterproof sealing of push-button switch.But, one end of volume film is sandwiched in the contact position of upper casing and lower casing, the other end of volume film only is inserted in the annular groove that is arranged on mast, the contact area of volume film and groove is little, and relative friction forces is little, and is too quickly or too fast when mast moves downward, the volume film is easy to spin off from the annular groove of mast, inner and the lower casing internal communication of the upper casing of push-button switch like this, namely the inside of push-button switch is communicated with the outside of push-button switch, so the reduction of the dustproof and waterproof sealing of push-button switch.
