G5 Series Basic Micro Switch in Screw Gun

Overview

The G5 Series Basic Micro Switch is a compact, snap-action control switch designed for reliable, repeatable switching in demanding small-tool and appliance applications (such as screw guns). Engineered for fast action and high sensitivity with a very small contact gap, the G5 delivers long mechanical life and stable electrical performance while supporting a wide variety of terminals and actuator styles. The series is offered in multiple temperature grades and carries worldwide safety approvals, making it suitable for global manufacturing and aftermarket use. 

Key Features

1. Compact structure & ultra-short contact gap — snap action design gives fast response, high sensitivity and minimal travel for precise actuation in tight assemblies. 

2. High durability & long life — engineered for extended mechanical cycles and robust performance under frequent actuation, reducing service/return costs. 

3. Global safety certifications — models in the G5 family are available with international approvals (UL/ENEC/CQC/CE/RoHS and similar), easing regulatory acceptance in multiple markets. 

4. Complete terminal & connection options — solder, PCB, quick-connect/tab and gilded terminals are offered to fit common production and repair practices. 

5. Multiple temperature grades — selectable material/insulation options for operating-temperature ranges 25T85, 25T125 and 25T150 to match application thermal requirements. 

6. Variety of operating handles/actuators — pin plungers, short/long hinge levers, roller levers and custom lever geometries let you tailor actuation force and travel for the screw-gun switch mechanism. 

7. Flexible electrical ratings — G5-type switches on the market commonly span compact ratings suitable for small tools and appliances (typical offerings range from low-current consumer ratings to heavier 5–16 A variants depending on model). (Refer to exact model datasheet for rating used in your screw gun design.) 

   
   

Typical Specifications 

• Contact form: SPDT / SPST variants available. 

• Operating force (OF): available across wide range (examples: 7 gf — 600 gf depending on actuator). 

• Temperature grades: 25T85, 25T125, 25T150. 

• Common terminal styles: solder, PCB, quick-connect (6.3 × 0.8 / 6.3 × 1.0 mm). 

Note: the exact electrical rating, mechanical life (cycles), IP rating, and PTI/insulation class vary by manufacturer/model — always confirm the specific G5 part number datasheet before design-in.

Application Fields

The G5 Series is widely used where compact, precise, and durable switching is required, including:

• Power tools / Screw guns: trigger and control circuits where short travel and fast response improve user feel and control.

• Household appliances: microwaves, dishwashers, rice cookers and timers where reliable on/off detection is needed. 

• Automotive electronics & instrumentation: small actuators, sensors and interlocks (when rated models & approvals are selected). 

• Consumer electronics & gaming controllers / light-guns: precise trigger detection with long life. 

• Medical & measurement devices, automation equipment: where dependable snap-action switching and global approvals matter. 

Why choose the G5 for a screw gun design?

• Extremely compact footprint to fit ergonomic handles.

• High sensitivity and short travel for crisp trigger feel.

• Multiple actuator/terminal choices to match manufacturing and service processes.

• Proven, widely produced family with global certifications — simplifies sourcing and compliance
