Widely used in CNC lathes, medical devices, automotive/e-bike modifications, computer hosts, home appliances, and instrument switches.

• Industrial Equipment: CNC machine tools, automated production line control panels for mode selection.
• Transportation: Automotive/e-bike modification switches, waterproof controls for ships and construction machinery.
• Medical Instruments: High-protection, precision-controlled medical device panels.
• Home Appliances & Electronics: Power switches for PCs, functional knobs for premium appliances (e.g., coffee machines, ovens).
• Harsh Environments: Outdoor instruments, agricultural machinery requiring dust/waterproofing and corrosion resistance.

• During installation, select the switch size corresponding to the device's installation aperture. Ensure the installation site is dry and clean. Avoid installing in environments with corrosive gases or severe vibrations to ensure the switch's normal service life.
• During operation, apply moderate force when rotating. Avoid excessive force to prevent damage to the switch's internal structure.
• Although the metal rotary switch is waterproof, avoid prolonged immersion in water to prevent degradation of its waterproof performance.
• When wiring, follow the instructions in the product manual to ensure correct and secure connections. Prevent short circuits or open circuits.
• Regularly inspect and maintain the switch. Clean surface dust and debris, and check whether rotation is smooth and contacts function properly.

Q1: Does IP65 rating support full submersion?

A: IP65 protects against water jets and dust but not prolonged submersion. For higher waterproofing (e.g., IP67/IP68), a custom sealing solution is required.

Q2: How to resolve knob jamming or unclear positioning?

A: This metal waterproof rotary switch selector switch may result from debris ingress or wear. Clean or replace the knob. Do not disassemble it, as this may compromise waterproofing.

Q3: Can the switch support custom positions (e.g., 4-position)?

A: Metal waterproof rotary switch selector switchStandard models are 2/3-position. Contact the manufacturer for custom multi-position or special-function designs.

Q4: How to choose between nickel-plated brass and stainless steel?

A:Nickel-Plated Brass: Superior corrosion resistance for humid/salty environments (e.g., ships, outdoor equipment).

Stainless Steel: Higher strength for impact-resistant industrial applications.

Q5: How to clean the metal knob surface?

A: Wipe with a soft cloth and neutral cleaner. Avoid strong acids/alkalis to prevent coating damage.
