The movable contact spring 100 adopts a pressure spring structure, is convenient to install and has low cost; the compression spring only works in a simple up-and-down motion, and the service life of the spring is very long; the invention uses two movable contact springs 100, which have great elasticity and can separate the contacts, thereby ensuring that the contacts are not bonded by high current. In summary, according to the practical requirements, the invention can be freely selected and arranged into five structures of 'single normally open', 'single normally closed', 'single normally open and normally closed', 'two normally open' or 'two normally closed', thereby achieving the purpose of expanding the application range of users; the contact structure can improve the load capacity, control the load of large current, has long service life of high load control, and has the advantages of convenient structure assembly and high production efficiency.
Preferably, the upper and lower edges of the first and second mounting portions 341 and 351 may be beveled edges, so that the movable contact 110 may perform friction self-cleaning with the first and second stationary contacts 120 and 140 during the up-and-down movement, thereby ensuring low-current load control performance and high sensitivity.
Further, a clasp 36 is formed at the lower part of the push rod 3 in a protruding manner, and the clasp 36 is positioned between the first push rod connecting part 34 and the second push rod connecting part 35; the base connecting part 41 is provided with at least two through holes, the base 4 can be penetrated with a self-locking hook 150 through the at least two through holes, the self-locking hook 150 is provided with two free ends 151, and the self-locking hook 150 can be hooked on the clasp 36 through the two free ends 151; two positioning rods 37 are fixedly arranged at one end of the push rod 3, and the clasp 36 is positioned between the two positioning rods 37. As shown in fig. 11, the self-locking hook 150 has two free ends 151, i.e. a bidirectional hook is adopted to balance the push rod 3, so that the self-locking performance is more stable and the hand feeling is more comfortable. The two positioning rods 37 can limit the position of the self-locking hook 150, which is beneficial to maintaining the stability of the structure.
The waterproof push-button switch of the present invention further comprises a fastening nut a screwed to the outside of the casing 1.
The invention can also be provided with an indicator light in the base connection part 41. The indicator lamp can be processed independently. The LED and the step-down resistor are subjected to spot welding by using a spot welding machine, the step-down resistor is welded on a pin workpiece by using the spot welding machine, the product percent of pass of spot welding is very high, the spot welding is independently processed, the whole processing and assembling process is very simple, the operation is easy, and the assembly and the product inventory are convenient.
The invention can freely combine accessories to realize multiple functions, including reset, self-locking, with or without indicator lights, etc., so as to freely combine the button switches with multiple functions.
The foregoing is illustrative of the present invention and is not to be construed as limiting the scope of the invention. Any equivalent changes and modifications can be made by those skilled in the art without departing from the spirit and principles of this invention, and are intended to be within the scope of this invention. It should be noted that, the components of the present invention are not limited to the above-mentioned overall application, and each technical feature described in the specification of the present invention may be selected to be used singly or in combination according to actual needs, so that other combinations and specific applications related to the present invention are naturally covered by the present invention.
