在产219 Series 6x6mm Tactile Switch
CTS 219 series standard 6x6mm tactile switch for automotive and industrial.
常见应用
CTS tactile switches are qualified for automotive dashboards — AEC-Q200 compliant with operating range to 105°C. Found in car HVAC controls, infotainment buttons, and instrument cluster interfaces. Also used in white goods (washing machines, dishwashers) and industrial membrane keypads.
规格参数
|
Actuation Force
The force needed to press the button. Lower = more sensitive. Sanwa ~65g (light), Seimitsu ~85g (medium), Happ ~130g (heavy).
|
180gf (1.77N)
|
|
Certifications
Third-party safety certifications. UL = required for US NEC installations. CE = EU compliance. CSA = Canadian standards.
|
AEC-Q200, UL
|
|
Mechanical Life
How many press cycles before mechanical failure. Higher is better — 10M cycles at 100 presses/day = 274 years.
|
500,000 cycles
|
|
Mounting Type
How the button attaches to the panel. Panel mount is standard — installs through a cutout from the front.
|
Through-hole and SMD
|
|
Max Operating Temp
Highest temperature the button is rated to operate in.
|
105°C
|
|
Travel Distance
How far the button moves when pressed. Shorter = faster response. Sanwa 0.85mm is extremely short for competitive gaming.
|
0.25mm

安装快速参考
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

故障排除
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
