DONGNAN Electronics provides you with professional product solutions, which can be customized according to drawings, and provide customers with satisfactory micro switches and waterproof switch products.
We have more than 30 years of experience in manufacturing switches We mainly produce micro switches, waterproof micro switches, push-button power switches, door control switches, rotary switches, voltage selector switches, etc..
DONGNAN ELECTRONICS CO.,LTD established in 1987, with more than 30 years manufacturing experience in making switches. Mainly produce micro switches, water proof micro switches, power switches, gate control switches, rotary switches, voltage-selected switches etc. We are a national-level new and high-tech switch manufacturing enterprise that has R&D, producing, marketing and after-sales service, and our switches are widely used in whole China and oversea countries.
Due to waterproof micro switches being in an enclosed or dusty environment for a long period of time, dust enters inside the switch through the gaps in the switch connections. As a result, dust may be attached to the contacts and metal plates of the switch, and it is recommended that sealed switches be used.
The first is high quality. The national requirements in the field of waterproof microswitch are very strict, which makes the manufacturer very meticulous in production. And our waterproof switches have obtained UL,CUL,TUV certificates to ensure the quality and stability of the switches.
The second is adaptability. Ordinary micro switches may cause problems such as short circuit of the switch in a humid environment. However, the waterproof micro switch has a strong waterproof force. It ensures that it can still maintain high strength in a humid environment and will not be damaged.
Waterproof micro switch can be installed in a variety of scenarios, but the main thing is to detect whether the internal movement of the parts reached a certain position, and so reach this position can achieve remote regulation, so now many artificial intelligence equipment are using micro switch, and the optimization of the micro switch is also doing better and better.
The micro switch and the traditional switch are actually similar, but the external form is very different, including rotary type, jacking type and so on. The core of the waterproof micro switch is still waterproof and safe and stable.
In the waterproof microswitch type, compared with semiconductor switches with waterproof microswitch characteristics, the function of the switch is achieved by means of a mechanical switch with contacts.
Micro switch is a kind of real pressure touch fast switch, also known as sensitive switch, its working principle is the external mechanical force through the transmission element to act on the action reed, and the energy accumulated to the critical point, after the instantaneous action, is the action of the yellow end of the moving contact and the fixed contact quickly connected, or disconnect the gas water heater, the micro switch is to control the start of the mechanical controller control ignition, when the water pressure reaches a certain time, the grinding disc inside will open the micro switch water heater ignition through the top of the transmission shaft, if the micro switch fails, The machine will not be able to ignite.
The production will be arranged after payment, and the delivery date depends on order quantity.
Better price for large quantity for one shipment.
