How to check the quality of Rocker switch

Rocker switches are also called rocker switches. Its structure is the same as that of a toggle switch, except that the handle of the button is replaced with a boat shape. Rocker switches are often used as power switches for electronic equipment. Their contacts are divided into single-pole single-throw and double-pole double-throw. Some switches also have indicator lights.

 

Switch type

Single pole single throw: 1 moving contact and 1 static contact. Only 1 channel

Single pole double throw: 1 moving contact and 2 static contacts, (the static contacts on both sides can be connected respectively)

Double pole single throw, 2 moving contacts and 2 static contacts, with 2 channels

Double-pole double-throw, 2 moving contacts and 4 static contacts, with 4 channels (2 static contacts on both sides can be connected respectively)

 

Detailed classification

Rocker switch is a small high-capacity power switch suitable for home appliances and office equipment. Compared with other switches, it is more powerful. But there are also different types of rocker switches.

  1. Small capacity non-sealed type

The rated voltage and rated current of this type of ship switch are relatively small, 5A @ 120VAC, 28VDC; 2A @ 250VAC. This type of product has three positions. In terms of material, the terminal is usually brass-coated with gold or silver. Long life span, up to 50,000 times. Such as ANR series

Electrical Ratings 5A @ 120VAC, 28VDC; 2A @ 250VAC

Electrical Life 50,000 cycles typical

Contact Resistance <20 mΩ max initial @ 2-4VDC, 100mA

Dielectric Strength 1500Vrms min

Insulation Resistance> 100MΩ min

Operating Temperature -40°C to 85°C

Storage Temperature -40°C to 85°C

  1. Large capacity sealed type

For large-capacity rocker switches, they are more suitable for use in power supplies, and the safety of the airtight is more guaranteed. 15A @ 125VAC; 8A @ 250VAC, there are two positions, ON or OFF, and the terminal material is brass-clad tin. Such as RA series

Electrical Ratings 15A @ 125VAC; 8A @ 250VAC

Electrical Life 10,000 cycles typical

Contact Resistance <50 mΩ initial

Dielectric Strength 1500Vrms min

Insulation Resistance> 100MΩ min

Operating Temperature -40°C to 85°C

Storage Temperature -40°C to 85°C

The above switch classification is basically American CIT switch relay (RIVERSUN (HONG KONG) LTD)

 

technical parameter

  1. Rated working voltage and current Rating 3A/6A/15A 250V
  2. Operating temperature range Temperature -25+85 ℃
  3. Contact Resistance <0.03Ω
  4. Actuating Force 1.3+0.5N
  5. Insulation Resistance >100MΩ
  6. Life (switching Life) 10000 times

 

Scope of application

Rocker switches are used in water dispensers, treadmills, computer speakers, battery cars, motorcycles, ion televisions, coffee makers, power strips, massage machines, etc., and are mainly used for household appliances.

 

The test method of ship switch life

Mainly test the number of opening and closing until it is damaged. If you do not need to manually use a small motor to drive the eccentric opening and closing switch, use a counter to record the number of times! This switch requires safety certification is necessary. If the product is sold in China, use CQC. If it is sold abroad, it depends on the specific country where it is sold, such as the United States UL, Canada CUL, and European countries have VDE, ENEC, TUV and other safety certifications.

Fault problem

The rocker switch is a very common kind of red light when it is switched on. Sometimes it can’t be turned off, just can’t bounce back, and it often jumps to the air switch failure

The method to solve the fault:

There is a metal piece inside the rocker switch with a spring fulcrum in the middle. The spring displacement and the aging and deformation of the plastic bracket make the switch inflexible. You can disassemble it after power off and have a look. If the plastic part is not damaged, it may be restored. The neutral wire inside the switch is straight through and has nothing to do with the switch components. Therefore, if the switch jumps to the air switch, the insulation layer of the neutral wire of the switch is damaged. You can cut off the damaged section and reconnect the wiring. Pay attention to the insulation to ensure . It may also be that there is a short circuit on the indicator light pin, just re-wire.

 

Method of choosing

  1. Is the certification complete?

Whether the waterproof rocker switch is fully certified, selected environmentally friendly materials, passed the relevant ROHS regulations, and has SGS certification; it has VDE/DEMKO/KEMA (currently using EU ENEC), UL/CSA and other certifications, only Arcolectric waterproof rocker switches can do well To the certification is complete.

  1. IP waterproof standard

The sealing performance of the waterproof rocker switch exceeds the standard. When paired with related accessories, it can reach IP65, IP66, IP67 or even IP68 waterproof rating.

  1. Design issues

Whether the waterproof rocker switch has reasonable design, long service life, high temperature resistance and high current impact resistance, these should be considered.

 

Precautions for use

The specific application of the waterproof rocker switch is restricted by many factors, such as: installation method and product installation direction, air flow, pressure difference acting on the product, fluid rebound strength and working voltage; etc. Even if the Arcolectric waterproof boat switch with excellent sealing performance, its sealing technology has reached the leading level, it also means that the switch is completely sealed, and it is necessary to prevent the intrusion of corrosive gases or substances.
