The Type 30-1XX series (including models 30-101 through 30-109) represents the Low Profile evolution of the classic Type 30 key switch. Manufactured by Pran Electronics, this series is designed for modern, slim-line electronic enclosures where vertical space is limited, but the premium “soft-touch” tactile feel of a high-end key switch is still required.

As a high-quality equivalent to the ITW Series 60 (Low Profile) and Stelvio Micro Code 500, the 30-1XX is a favorite for front-panel interfaces in medical and laboratory instrumentation.

Key Advantages of the 30-1XX Series

• Space-Saving Vertical Profile: With a total height of only 12mm, these switches are 20% shorter than the standard 30-200 series. This allows for thinner product casings and more compact stacking of PCBs in multi-layered devices.

• Integrated Keycaps: Unlike the 30-200 which usually requires a secondary knob, the 30-1XX series often comes with the plunger and keycap as a single, low-profile unit. This reduces the total component count (BOM) and assembly time.

• Premium Tactile Response: Despite its smaller stature, it maintains the famous “Pran Type 30” feel—a quiet, soft-bottoming action that feels significantly more professional and durable than a standard “clicky” 6x6mm tact switch.

• Robust 4-Pin Mounting: The 4-pin through-hole layout provides exceptional mechanical stability. The internal bridging (Pins 1-2 and 3-4) allows the switch to function as a PCB jumper, simplifying trace routing on single-sided boards.

Material & Environmental Performance

Pran Electronics utilizes high-grade materials to ensure performance in demanding environments:

• Base & Plunger: High-temperature, flame-retardant industrial thermoplastic.

• Contacts: Phosphor Bronze with Heavy Silver Plating for superior electrical conductivity and resistance to oxidation.

• Sealing: Designed to resist flux contamination during the wave soldering process.

• Temperature Range: Fully operational from -30°C to +85°C.

Common Applications

• Handheld Medical Devices: Portable monitors, infusion pumps, and diagnostic testers.

• Compact Lab Equipment: Digital stirrers, pH meters, and centrifuges.

• Telecommunications: High-end intercom systems and networking hardware reset/function buttons.

• Professional Audio/Video: Control consoles and rack-mounted processing units.

• Electronic Scales: Low-profile bench scales and jewelry scales.
