Momentary Push Button Switch For Power Tools

Built for harsh, high‑vibration environments, this momentary push button switch provides reliable, non‑latching control for corded and cordless power tools. A sealed front bushing with o‑ring and optional rubber boot achieves IP65–IP67 protection against dust, oils, and wash‑down, while a reinforced mechanism delivers long life under repetitive use. Available with SPST (NO/NC) or SPDT contacts and silver or gold plating, it supports both higher‑current control circuits and low‑level logic inputs to a motor controller. The low‑profile, anti‑vandal metal or polymer actuator is easy to operate with gloves and resists impact. Termination options include solder lugs, PCB pins, quick‑connect tabs, and pre‑wired silicone leads to simplify assembly on tool lines.

IP sealing and durability:

• IP65 jet‑proof standard; IP67 front‑panel sealing option (1 m, 30 min when properly mounted)
• Front o‑ring plus optional silicone boot for unmated sealing; rear gasket available
• Resistant to oils, cutting fluids, dust, and debris; UV‑stable options for outdoor tools
• Shock/impact resistant actuator and bushing; IK07–IK09 options (verify per model)
• Vibration‑proof hardware: locknut, star washer; optional threadlocker pre‑applied

Electrical (typical, verify per datasheet):

• Function: momentary (spring‑return), normally open standard; NO/NC or SPDT variants
• Ratings (representative): up to 3 A at 250 VAC; 5 A at 125 VAC; 3 A at 30 VDC (resistive)
• For low‑level signals: gold‑plated contacts for 5–24 V logic and relay/driver inputs
• Contact resistance: ≤50 mΩ initial; insulation resistance: ≥100 MΩ at 500 VDC
• Dielectric withstand: 1,000 VAC, 1 minute
• Optional LED indicator (dot/ring) with series resistor options for 3/6/12/24 V

Mechanical:

• Actuation type: momentary, spring‑return; tactile feedback for positive confirmation
• Mechanical life: 200,000–1,000,000 cycles (load dependent)
• Travel: 1.5–3.5 mm; actuation force: 2.5–6 N typical (glove‑friendly)
• Operating temperature: −25 to +85 °C (extended −40 to +105 °C on request)
• Materials: stainless steel or nickel‑plated brass bushing; high‑temp UL94V‑0 plastics (PBT/PA66/LCP)
• Panel cutouts commonly 10/12/16/19 mm; panel thickness 1–6 mm; low‑profile or raised actuator styles
• Terminations: solder lugs, 2.8/4.8 mm quick‑connect tabs, PCB pins, or pre‑wired silicone leads (e.g., 18–22 AWG)

Applications:

• Cordless drills/drivers, impact wrenches, grinders, rotary tools
• Circular/reciprocating/jig saws, sanders, planers
• Hammer drills and demolition tools with dead‑man operation
• Lawn and garden tools: trimmers, blowers, hedge cutters
• Compressors, portable pumps, and jobsite equipment HMIs
• Jig fixtures, testers, and shop power stations

Customization options:

• Contact block: SPST (NO/NC), SPDT; dual‑pole variants for double‑break circuits
• Sealing: IP65 standard, IP67 front‑face; rubber boot styles and colors
• Actuator: flat/raised/domed; knurled or textured surface for grip; large cap for glove use
• Illumination: ring/dot, color (R/G/B/W/amber), independent or follow‑contact wiring; LED voltage presets
• Materials/finish: stainless 304/316, black‑anodized aluminum, nickel‑plated brass; polymer bushing for weight saving
• Termination: quick‑connect tabs, solder, PCB, or factory‑crimped wire leads with connectors
• Contact plating: silver for higher current; gold‑over‑nickel for low‑level signals and corrosion resistance
• Force/travel tuning for specific ergonomics; silent or clicky feel
• Markings: laser‑engraved icons (power, start, PTT), color rings, custom logos

Design notes:

• For inductive loads (motors/solenoids), use snubbers or flyback diodes to extend contact life
• Maintain specified panel cutout finish and nut torque to preserve IP rating and vibration resistance
• Consider gold contacts if switching only logic/enable lines to a motor controller
• Do not use as a safety‑rated emergency stop without appropriate certified components and circuit design
