FAQ: Toggle Switches
Q1: How do I choose between light-, heavy-, and extra-heavy-duty?
Match the electrical rating (current/voltage, AC/DC), mechanical life, and environmental rating to your use. Heavy- and extra-heavy-duty toggles typically offer higher amp ratings, stronger bushings, and better resistance to shock/vibration—ideal for commercial vehicles, construction, and agriculture.
Q2: What IP rating do I need?
-
Indoor/dry panels: IP40–IP50 is often sufficient.
-
Dusty or splash areas: Aim for IP65/66.
-
Direct wash-down or marine exposure: Choose IP67/68 and consider a sealing boot over the actuator.
Q3: Marine vs. sealed “waterproof” toggles—what’s the difference?
Marine-grade toggles pair high sealing (IP67/68), corrosion-resistant hardware (stainless/brass), and UV-resistant actuators. “Waterproof” may only describe ingress protection; for salt fog and long-term UV, confirm salt-spray and material specs.
Q4: Which circuits are most common?
-
SPST (ON-OFF) for simple power.
-
SPDT (ON-ON / ON-OFF-ON) for signal routing or two-source selection.
-
DPDT to switch two poles simultaneously or reverse polarity (e.g., motor direction). Check momentary options if spring-return is required.
Q5: Can I get illuminated toggle switches?
Yes. Look for LED-illuminated or neon lamps. Verify supply voltage for the lamp circuit, and whether illumination is independent or tied to the switch position.
Q6: What about mounting and panel cutouts?
Most toggles use threaded bushings (¼-40, M6, M12, etc.) with a panel nut. Confirm bushing length, anti-rotation features (D-flat or keyed), and panel thickness. Marine versions often add sealing washers and boots.
Q7: Solder lugs, screw terminals, or quick-connects?
-
Quick-connect (fast-on) for field serviceability.
-
Screw/Stud for high current and rugged installs.
-
PCB pins for board-mount assemblies. Choose based on current, assembly process, and service needs.
Q8: Approvals and compliance?
For vehicles and safety-critical systems, check UL/CSA, ENEC, or mil/aviation approvals as applicable. Also verify RoHS/REACH compliance and operating temperature (commercial vs. extended range).
Q9: How do I replace an existing toggle?
Match circuit function (SPST/SPDT/DPDT), electrical rating, mechanical form (bushing size/length), terminal type, and environmental rating. When in doubt, cross-reference by series and datasheet dimensions.
Q10: What accessories should I consider?
-
Sealing boots (rubber or silicone)
-
Switch guards/safety covers (to prevent accidental actuation)
-
Panel nuts, lock washers, nameplates
-
Dust caps for unused terminals
