SUNTAN TECHNOLOGY COMPANY LIMITED · ALL KINDS OF CAPACITORS

Most selection decisions around a 6×6 mm tactile switch come down to four key parameters: operating force, actuator height, mounting method (TH vs SMD), and mechanical travel consistency.

This guide summarizes these parameters purely based on the official Suntan datasheets and shows how to quickly map your mechanical constraints and fingertip feel requirements to the right part number.

Key 6×6 mm Tactile Switch Series Covered

All models below share a common 6×6 mm footprint while offering different actuator heights, operating forces and mounting options for appliance, industrial and module-based designs.

Suntan TSS-TC-12XA 6x6mm tactile switch with multiple actuator height options from 4.3mm to 15mm for control panel design
TSS-TC-12XA – Multi-height actuator options (4.3–15 mm, TH)
Suntan TSS-TC-0010 low-profile 6x6mm tactile switch with 3.8mm actuator height for compact keypads

1. Mechanical Travel Consistency (0.25 ± 0.1 mm)

All Suntan tactile switches in the 6×6 mm category share the same mechanical travel:

  • 0.25 ± 0.1 mm travel

Covered series:

  • TSS-TC-0010 (Through-Hole)
  • TSS-TC-12XA / TSS-TC-12XT (Through-Hole)
  • TSS-TD-03XG / TSS-TD-06XG (SMD)

Engineering relevance
A uniform travel spec helps maintain predictable tactile feedback, reduces variation between production batches, and stabilizes interface behavior in appliance, industrial, and module-based designs.

High-intent keywords: tactile switch travel distance, momentary switch actuation, 6x6 tactile switch mechanical structure.

2. Operating Force Options (100–250 gf)

Operating force is one of the most critical parameters affecting the user’s tactile feedback and perceived quality of the interface.

SMD series: TSS-TD-03XG / TSS-TD-06XG

The following operating force codes are available:

  • 100 ± 30 gf (T)
  • 130 ± 30 gf (V)
  • 160 ± 50 gf (X)
  • 170 ± 50 gf (W)
  • 190 ± 50 gf (Y)
  • 250 ± 100 gf (Z)

Through-Hole series: TSS-TC-0010 / TSS-TC-12XA / TSS-TC-12XT

Available operating force codes:

  • 160 ± 50 gf (X)
  • 250 ± 100 gf (Z)

Engineering interpretation

  • 100–130 gf: Light-touch interfaces, short key travel, frequent rapid presses.
  • 160–170 gf: Standard feedback for general control panels and appliance keys.
  • 190–250 gf: Glove operation, vibration-prone environments, deliberate actuation only.

High-intent keywords: tactile switch force options, 160gf tact switch, 250gf industrial switch, momentary switch operating force comparison.

3. Actuator Height Selection (3.8–15 mm)

Choosing the correct actuator height prevents enclosure mismatch, unwanted pre-load, or insufficient key travel. All height values below are taken from Suntan’s 6×6 mm tactile switch datasheets.

Through-Hole (TC series)

TSS-TC-12XA height options:

4.3 / 5 / 6 / 7 / 8 / 8.5 / 9 / 9.5 / 10 / 11 / 12 / 13 / 14 / 15 mm

TSS-TC-0010 height: 3.8 mm

These options allow designers to compensate for front-panel thickness, overlay stacks and mechanical tolerances while keeping the same electrical and tactile behavior.

High-intent keywords: tact switch actuator height, 6x6mm tactile switch dimensions, momentary switch stem height options.

4. Height × Operating Force Quick Comparison

The matrix below combines the available actuator height range (3.8–15 mm) with the operating force options (100–250 gf). It is intended as a quick reference when balancing enclosure mechanics and fingertip feel.

Height range (mm) Operating force range (gf) Typical feel Typical design scenarios
3.8–6 mm
(e.g. TSS-TC-0010, lower TSS-TC-12XA heights)		 100–130 gf Light, quick press Compact keypads, low-profile modules, handheld devices where users press frequently and expect low fatigue.
3.8–6 mm 160–170 gf Standard, well-defined click General-purpose control panels, white goods, audio front panels where a clear confirmation click is preferred without being too heavy.
7–10 mm
(mid-height TSS-TC-12XA options)		 160–170 gf Standard, pronounced feedback Products with thicker overlays or decorative panels, where additional height is needed to reach the user while keeping typical tact switch feel.
7–10 mm 190–250 gf Heavy, deliberate press Industrial panels, test equipment and machinery with possible vibration, where accidental operation must be minimized.
11–15 mm
(tallest TSS-TC-12XA options)		 160–170 gf Extended stem, standard force Deep enclosures, designs with keycaps or decorative knobs mounted above the tact switch, while preserving familiar tactile response.
11–15 mm 190–250 gf Extended stem, heavy force Ruggedized or outdoor interfaces, glove operation, and applications where users must confirm the press through a strong click even on tall actuators.

How to use this matrix:

  • Start from mechanical constraints: panel thickness, enclosure depth, required stem height.
  • Select force range: lighter for frequent presses; heavier for noisy or glove environments.
  • Pick part number: choose the TC/TD series and code combination that matches your row in the table.

Why Engineers Ditch Batteries for Supercapacitors – Inside TS12 Tech

In next-generation IoT devices, smart meters, and embedded controllers, engineers are replacing chemical batteries with supercapacitors to achieve stable, maintenance-free power backup. The Suntan TS12 Series leads this transition with gold capacitor energy storage that combines high reliability, low ESR, and long lifetime performance.

Battery Limitations vs. Supercapacitors

Conventional batteries degrade quickly under repetitive charge–discharge cycles and extreme temperatures. They often fail to sustain memory modules or communication chips during voltage drops. In contrast, supercapacitors vs batteries excel by offering instant energy release and nearly unlimited cycle life.

Meet the TS12 Gold Capacitor Family

The Suntan TS12 Series provides 5.5V–6.3V rated options with compact size and outstanding endurance, ideal for stable energy storage and voltage backup.

  • Operating Range: −25°C to +70°C (wide industrial range)
  • Capacitance: 0.047F–1.0F typical (expandable up to 3000F for high power models)
  • Cycle Life: >100,000 charge/discharge cycles
  • Compliance: Pb-Free, RoHS

Engineer’s choice: Compact backup for data loggers and communication nodes requiring stable voltage retention after power loss.

Technical Insight: Energy Density, Power Density & Internal Resistance

Energy Density (Wh/kg)

TS12 supercapacitors achieve 2–10 Wh/kg — lower than Li-ion batteries but optimized for instant power delivery. This makes them ideal for short-term backup or bridging power gaps.

Power Density (W/kg)

With up to 10,000 W/kg, the TS12 handles peak current surges where batteries lag. In industrial PLCs and solar inverters, this ensures uninterrupted logic control during brownouts.

Internal Resistance (ESR)

TS12 features a low ESR design—typically below 50 mΩ for radial types—reducing heat buildup and voltage drop. Ideal for real-time energy recovery in high reliability energy components such as UPS modules and EV auxiliary systems.

Application Environments

From smart factories to renewable energy systems, TS12 delivers maintenance-free operation even under humidity, vibration, and temperature stress. 

From the Supercapacitor vs Battery Debate to Real-World Reliability

When comparing supercapacitor vs battery systems, engineers look beyond capacity — they evaluate cycle life, ESR stability, and thermal reliability. The Suntan TS12 Series offers consistent energy storage and power backup for IoT devices, outperforming batteries in frequent charge/discharge environments.

In real-world applications such as smart meters and solar controllers, the TS12 provides a maintenance-free energy solution that minimizes service interruptions. Its low ESR capacitor structure ensures stable voltage during load switching, which is critical for embedded electronics and data stability.

High Reliability Energy Components for Critical Systems

Each TS12 variant is part of Suntan’s high reliability energy components lineup. The industrial supercapacitor module supports buffering in UPS systems, EV auxiliary circuits, and industrial PLCs where rapid power recovery is essential.

By integrating gold capacitor energy storage technology with low internal resistance, the TS12 family ensures long-term stability even under temperature swings and vibration, providing dependable performance for critical embedded systems.
