Full Range Tact Switches, Perfectly Matched for Household Appliances, Digital Products, Automotive & Industrial Control Applications

1. 6×6mm Vertical SMD Tact Switch (Most Popular Standard Type)

Application: Remote controls, speakers, TVs, small home appliance panels
Selection Key Points:

  1. Heights ranging from 0.8~5.0mm for selection; common sizes 1.5/2.0mm

  2. Standard actuation force: 160gf; 60gf for slim digital devices; 250gf for anti-misoperation

  3. 100,000 cycles with thin gold plating for dry indoor use; upgrade to IPX4 waterproof for humid kitchen & bathroom environments

  4. Supplied in SMT tape & reel; high-temperature resistant LCP base compatible with lead-free reflow soldering

2. 4×4mm Ultra-thin SMD Tact Switch

Application: Power banks, smart wearables, earbud cases, compact digital gadgets
Selection Key Points:

  1. Prioritize ultra-thin versions 0.8/1.0mm for limited structural space

  2. Low actuation force 60~100gf; silent non-click version optional

  3. Designed for low-current signal load within 5V 50mA

  4. Not recommended for humid environments; no standard waterproof structure

3. 3×3mm Micro SMD Tact Switch

Application: Bluetooth earphones, smart bracelets, miniature sensors, compact portable devices
Selection Key Points:

  1. Extra compact size; PCB pads must strictly match specifications

  2. Short travel & soft tactile feel; typical service life 100,000 cycles

  3. Only for weak electric signals, cannot carry heavy loads

  4. Unsuitable for frequent pressing or humid working conditions

4. Horizontal Side-Actuated Tact Switch (2×3 / 3×4 Side Push)

Application: Mobile phone side keys, power bank side buttons, earbud case side switches
Selection Key Points:

  1. Horizontal mounting; pay attention to overall height limit

  2. Versions with top bracket / bracketless; alignment posts to prevent reverse assembly

  3. Low-height versions for ultra-slim devices with soft actuation force

  4. Gold-plated contacts with 200,000 cycles for frequent power on/off keys

5. Tact Switch with Plastic Bracket

Application: Washing machines, induction cookers, water dispenser panels
Selection Key Points:

  1. Plastic clip bracket locks onto housing without screws

  2. Standard IPX4 splash-proof, ideal for kitchen & bathroom scenarios

  3. High temperature resistance to fit high-temperature operating environments of complete machines

6. IPX7 Fully Waterproof Tact Switch

Application: Water heaters, smart toilets, outdoor equipment, cleaning instruments
Selection Key Points:

  1. Full silicone sealing structure, supports temporary water immersion

  2. Gold-plated contacts mandatory to avoid poor contact caused by moisture oxidation

  3. Standard temperature range: -20~70℃; automotive grade upgraded to -40~85℃

  4. Higher unit price than standard models; reserve extra budget accordingly

7. LED Illuminated Tact Switch

Application: Power buttons, industrial control equipment, desktop chargers
Selection Key Points:

  1. Single-color / dual-color LED options, match supply voltage

  2. Reserve current-limiting circuit for LED on PCB

  3. Uniform light transmission housing to avoid light leakage

  4. Gold-plated long-life version for high-frequency operation

8. DIP Through-Hole Tact Switch

Application: Traditional home appliances, simple controllers, hand-soldered prototypes
Selection Key Points:

  1. Standard 2.54mm pin pitch, compatible with wave soldering

  2. Metal fixing lugs to lock panel and prevent wobbling

  3. Not recommended for mass production; lower efficiency than SMD types

9. Automotive High-Longevity Tact Switch

Application: Car head units, steering wheel buttons, vehicle central control
Selection Key Points:

  1. Wide temperature range -40℃~+85℃, resistant to oil & cleaning agents

  2. Extra-long service life 1,000,000 cycles with thick gold-plated contacts

  3. High ESD protection ≥ ±8kV

  4. Prioritize models certified to AEC-Q200 standard

10. 2-Step Dual-Stage Tact Switch

Application: Camera shutters, light dimming / speed regulation buttons
Selection Key Points:

  1. Two independent signal circuits: half-press for first stage, full-press for second stage

  2. Obvious difference in actuation force between two stages for distinct layered tactile feedback

  3. Circuit requires two separate IO ports to receive dual signals
