3PDT Slide Switch For Electric Fan

Robust 3PDT slide switch designed for electric fans and small home appliances. Provides simultaneous switching of three independent circuits, ideal for speed selection (Low/Medium/High), capacitor tap routing, or multi-function control in AC fan designs. Smooth, positive detents with a reinforced metal bracket ensure reliable operation under vibration. Available for PCB through‑hole mounting or panel installation with solder lugs.

Key features and specifications:

• Switch type: 3PDT slide; actuation options: ON‑ON, ON‑OFF‑ON, or ON‑ON‑ON (model‑dependent)
• Mounting: PCB THT (straight/angled pins) or panel mount with bracket; optional locating pins
• Terminals: tin‑plated copper‑alloy pins or solder lugs; optional 2.8 mm quick‑connect tabs
• Electrical ratings: 125 VAC 3–4 A; 250 VAC 2–3 A; 12/24 VDC up to 3 A (derate by model and load type)
• Electrical performance: contact resistance ≤50 mΩ; insulation resistance ≥100 MΩ (@500 VDC); dielectric strength 1500 VAC/1 min
• Mechanical performance: travel ~3–5 mm; operating force 1.5–3.0 N; crisp detents; mechanical life ≥20,000 cycles
• Materials: flame‑retardant PA66/PBT housing (UL 94 V‑0); copper‑alloy contacts with silver/nickel plating; stainless/nickel‑plated slider and bracket
• Environment: operating temperature −20 to +85 °C; dust protection to IP40; suitable for indoor appliance use
• Compliance: RoHS/REACH; designed to align with IEC/EN 61058 and relevant appliance standards (model‑dependent)

Applications:

• Three‑speed selection in AC fans via winding/capacitor tap switching
• Mode selection (power, timer, oscillation light circuit) in fan control panels
• Multi‑circuit control in small household appliances and air movers

Options and customization:

• Actuator length/shape/color; center‑off or continuous three‑step logic
• Gold‑plated contacts for low‑level signal reliability
• Extended bracket, anti‑loosening hardware, custom PCB footprint and marking plates

Design notes:

• For mains applications, observe creepage/clearance on the PCB and insulation class; switch the line conductor per local regulations
• Apply derating for inductive loads and motor inrush; use RC snubbers or diode suppression where appropriate
• Not recommended to switch high starting currents or compressor motors directly; pair with relays/triacs/contactors
• Verify pole/function mapping, wiring, and panel cutout before design‑in; follow soldering profiles and prevent solvent ingress during cleaning
