The appliances we use every day at home or in our business establishments consist of several essential components. These components are also made up of smaller devices and parts that are carefully assembled to allow our appliances’ smooth and accurate operation.
One of the smaller devices that make up the components of the machines we use is the LED pilot light. It is one of the most reliable indications of whether a certain device operates well. Let’s define these lights, applications, benefits, specifications, etc.
Waterproof push button switches, as the name suggests, are switches that can be operated with wet hands. In some humid environments, it can be used with confidence because it has good sealing performance. The highest IP rating of the waterproof switch is IP68. The waterproof button switch has a reasonable design, long service life, high temperature resistance, and current shock resistance, which can meet your specific use needs.
Precautions
The specific application of these waterproof switches is restricted by many factors, such as the installation method and the installation direction of the product, the pressure difference of the airflow acting on the product, the strength of the fluid rebound and the working voltage. We also need to prevent the intrusion of corrosive gases or the intrusion of substances.
The waterproof metal switch cooperates with the circuit breaker to perform switch operations according to the needs of the system operation mode, and change the system operation wiring mode.
Classified according to the purpose and structure of the contact
(1) Normally open button
(2) Normally closed button
(3) Compound button classified according to operation mode and protection mode Buttons can be classified according to operation mode and protection mode, common button categories and characteristics:
(1) Open type: suitable for embedded and fixed on the panel of switch board, control cabinet or console.
(2) Protective type: with a protective shell, which can prevent the internal button parts from being mechanically damaged or people touching the live parts.
(3) Waterproof type: with a sealed shell, which can prevent rainwater from intruding.
(4) Anti-corrosion type: it can prevent the intrusion of chemical corrosive gases.
(5) Explosion-proof type: It can be used in places containing explosive gas and dust without causing explosion transmission, such as coal mines and other places.
(6) Illuminated button: There is a signal light inside the button, which is not only used to issue operation commands, but also serves as a signal indicator, and is mostly used on the panels of control cabinets and consoles.
(7) Key type: Insert and rotate with a key to operate, which can prevent be operated by a special person.
(8) Emergency type: There is a big red mushroom button protruding outside, which is used to cut off the power supply in case of emergency.
(9) Self-holding button: The button is equipped with a self-holding electromagnetic mechanism, which is mainly used in power plants, substations or test equipment. Operators communicate with each other and issue instructions, etc., and are generally panel-operated.
(10) Knob type: The contact is operated by rotating the handle, with two positions of on-off, generally panel-mounted.
(11) Combined type: combination of multiple buttons. (12) Interlocking type: Multiple contacts interlock with each other. Code-named off, on.
