Key Features
Main circuit: usually support 250V 3A, to meet most of the equipment power control needs;
Indicator light circuit: low voltage DC power supply (6-24V), power consumption <0.5W, optional red/blue/green/blue/white light colors;
Contact material: silver alloy contacts, reduce resistance, reduce arc, improve service life.
FAQ
1.How it works?
Mechanical Trigger Structure
Press operation: When pressing the metal button, the internal spring mechanism drives the contact module to move, so that the main circuit contact closes (energized) or disconnects (de-energized), directly controlling the power supply of the equipment.
Self-locking/self-resetting optional: some models support self-locking (press once to keep energized, press again to de-energize) or self-resetting (press and hold to energize, release to de-energize), adapting to different control needs.
2.Can this metal pushbutton switch be used for outdoor work?
Designed to cope with outdoor operating environments, this metal push button waterproof switch is capable of stable and reliable operation.
IP65 rated waterproof and dustproof
Waterproof: it can withstand spraying water and heavy rain, preventing rainwater from penetrating into the internal circuit.
Dustproof: Fully sealed structure blocks sand and dust, suitable for dusty environments such as deserts and construction sites.
Corrosion and Weather Resistance
Metal Material: Brass/stainless steel housing resists salt spray corrosion, suitable for coastal, chemical plants and other humid environments with salty air.
Temperature resistance: the working temperature range is usually -25℃～+55℃, adapting to cold or sunshine scenes (such as outdoor equipment in winter and open-air machinery in summer).
Impact resistance and durability
High protection level of the metal casing can withstand the common outdoor vibration, bump or accidental drop impact.
More than 50,000 cycles of mechanical life, durable, reducing the cost of frequent replacement.
