Product Overview
The LXW20-11M is a stepped magnetic blow-out micro switch designed for industrial switching and position control applications. It features a rubber covered stepped plunger actuator, magnetic arc extinguishing structure, and reliable snap-action contact mechanism.
The stepped plunger design controls pressing travel and helps prevent excessive mechanical impact on the internal spring structure. The rubber cover improves protection against dust, impact, and environmental contamination.
LXW20-11M is suitable for elevators, machinery, household appliances, workshop equipment, safety interlocks, and precision automation systems.
Product Display
The LXW20-11M uses a compact flame-retardant plastic housing with side mounting holes, clear terminal identification, rubber covered plunger actuator, and internal magnetic blow-out arc extinguishing components.
