Product Description

WEIPENG® is a leading HK-04G-L5a 125 V250V Micro Switch Bent Lever Two Pins manufacturers, suppliers and exporter.

Micro Switch Introduction

The HK-04G-L is a 2-pin SPST snap action micro switch with a bent lever arm. Belongs to the classic snap-action structure; it relies on a high-precision internal spring and leaf mechanism. When external force presses the lever to the critical point, the internal contacts switch instantly, without slow contact sparks. It can switch the COM terminal between the normally open (NO) and normally closed (NC) circuits, with precise operation and crisp rebound, effectively reducing arcing and extending the overall service life.

Rated at 5A 250V AC, it features high-quality AgNi alloy contacts, flame-retardant PBT housing and wide operating temperature from -25℃ to 125℃.With ultra-short actuation travel and fast snap-action mechanism, it ensures stable circuit switching, low arcing and long mechanical life over 1,000,000 cycles. Certified by UL, VDE, ENEC, CE and CQC, it is widely applied in home appliances, kitchen devices, power tools, industrial limit control and safety interlock systems.Tongda HK-04G-L micro switch maintains consistent performance, precise actuation and universal mounting size, perfectly suitable for mass production and aftermarket replacement.

Micro Switch Application

With features such as small size, SPDT double-circuit switching, high temperature resistance, and long service life, the applications are extensive:

Kitchen small appliances: safety switches for air fryers, microwaves, ovens, and electric fryer doors

Small industrial/electric equipment: limit switches for power tools, small machinery, electric actuators, and lifting equipment

Home electronics: interlocking protection for smart door locks, small instruments, and equipment covers

Automotive accessories: small onboard control mechanisms, seat/sunroof position detection switches

General maintenance replacement: universal replacement for various old micro switches of the same specifications
