Introduction to sealed micro switch

A sealed switch is an electrical switch that completely isolates its internal contacts from the external environment through a special construction. It typically uses technologies such as rubber diaphragms, silicone sleeves, or epoxy resin potting to achieve a specific protection rating (IP65 or IP67).

Three Key Features and Advantages

◆ Extreme Environmental Adaptability: Completely isolates the switch from dust (preventing poor contact), moisture (preventing short circuits), and grease or corrosive chemical gases, enabling stable operation under extremely harsh conditions.
◆ High Reliability and Long Lifespan:Because the contacts are not in contact with air, oxidation and carbon buildup caused by electric arcing are effectively avoided, significantly reducing the failure rate and greatly extending the switch's service life.
◆ Stable Performance:Under vibration, high and low temperature shocks, or high humidity environments, the sealed structure maintains stable trigger torque and electrical parameters, preventing malfunctions.

Sealed Micro Switch Application

Sealed micro switches have been widely used across various industries.

In home appliances, sealed micro switches can be used in ice makers, mainly to detect the water level and the ice cubes. When the water level or the height of the ice accumulation reaches a certain point, these switches are triggered and quickly send a signal to stop the inflow of water or the production of ice cubes.

In automotive industry, sealed switches are primarily used as door lock switches to check whether the car doors are fully locked, preventing serious safety hazards that could arise from driving with doors not properly secured.

In industrial equipment, sealed switches are mainly used in small limit switches of automated devices to check whether the equipment is operating normally and to detect any overtravel conditions.
