Product Description

This soft-touch rocker is engineered for harsh industrial environments where operators wear gloves and need a non-slip, comfortable actuator. The overmolded TPE/silicone surface provides secure grip and damped feel, while internal snap-action, quick-make/quick-break contacts handle high AC loads and motor inrush reliably. A front gasket and sealed actuator deliver IP65/IP67 protection against dust and washdown splashes when correctly mounted. Choose illuminated versions (LED or neon) for clear ON/OFF indication and night visibility, with independent light circuits for flexibility. Multiple pole/throw options (SPST, SPDT, DPST, DPDT; maintained or momentary; center-off) fit power, enable, and mode select functions in machine panels. Terminations include 6.3 mm quick-connect tabs, solder lugs, or PCB pins, and housings in UL94V-0 materials ensure flame resistance. Snap-in bezels speed installation, while screw-mount frames add security under vibration.

Key features:

  • Soft-touch rubberized actuator; high grip, glove-friendly
  • Front sealing to IP65/IP67 with integrated gasket (proper mounting required)
  • Snap-action, quick-make/quick-break contacts for reduced arcing
  • High current ratings for AC mains and motor loads
  • Illumination options: single/dual LED or neon, independent circuits
  • Configurations: SPST, SPDT, DPST, DPDT; maintained, momentary, or center-off
  • Mounting: snap-in bezel or screw-mount frame; standard panel cutouts
  • Terminations: 6.3 mm (0.250") quick-connect, 4.8 mm tabs, solder lugs, PCB pins
  • High-contrast legends (I/O, ON/OFF) and custom icons available
  • UL, cUL, ENEC, VDE approvals; UL94V-0 housings; RoHS/REACH compliant

Typical specifications (verify per selected datasheet):

  • Electrical rating: up to 16 A @ 250 VAC or 20 A @ 125 VAC (resistive); motor/HP ratings per approval
  • Inrush capability: motor and lamp loads supported; derating applies
  • Contact material: silver alloy (AgSnO2 or AgNi) for power loads
  • Contact resistance: ≤50 mΩ initial
  • Insulation resistance: ≥100 MΩ at 500 VDC
  • Dielectric strength: 1,500 VAC, 1 minute
  • Mechanical life: 50,000–100,000 cycles (maintained); lower for momentary options
  • Electrical life: 10,000–50,000 cycles at rated load (series dependent)
  • Operating temperature: −25 to +85 °C (extended ranges available)
  • Panel sealing: IP65/IP67 front with gasket; back of panel non-sealed unless specified
  • Panel cutouts: standard sizes (e.g., 30×22 mm, 19×13 mm mini); thickness 1–3 mm typical

Applications:

  • Machine tools, CNC enclosures, and auxiliary equipment (power, coolant, light)
  • Conveyors, packaging, and material handling systems (enable/mode select)
  • Pumps, compressors, and HVAC units (start/stop, fan speed)
  • Industrial washers and food-processing equipment (washdown-ready operator controls)
  • Agricultural and construction machinery panels
  • Test benches, power distribution boxes, and service carts

Customization options:

  • Actuator: contour, color (black, red, green), soft-touch overmold type, backlit lens window
  • Legends: I/O, ON/OFF, speed icons, text, laser-etched or pad-printed
  • Illumination: LED colors/voltage (5–24 VDC, 125/250 VAC), neon options, independent wiring
  • Poles/throws: SPST–DPDT; maintained/momentary; center-off; interlocked versions
  • Sealing: standard splash-proof to IP65; enhanced IP67 front seal; rear sealing boots
  • Mounting and cutout: snap-in or screw; bezels for thicker panels; anti-rotation features
  • Terminations: tab size, solder lug orientation, PCB pin pitch; harness pre-assembly
  • Materials: low-temperature elastomers; anti-sulfur contact finishes; high UV resistance

Design notes:

  • Not a safety E‑stop: use certified mushroom E‑stop for emergency functions.
  • For inductive loads, add RC snubbers or MOVs across the load to limit arcing and extend contact life.
  • Confirm horsepower/motor ratings and agency approvals for your mains voltage and category.
  • Ensure proper panel cutout and gasket compression to achieve IP rating; avoid paint buildup on sealing surfaces.
  • Use appropriate female quick-connects with retention and insulation sleeves; verify crimp pull-out strength.
  • Separate illumination circuits from switched mains if using low-voltage LEDs; observe polarity.
  • Consider vibration: prefer screw-mount or locking snap-in, and route wiring to relieve strain.
  • Provide clear operator labeling and backlighting for low-light environments; test glare through viewing angles.
