Long-Leg Handle Reset Miniature Micro Switch

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.

Due to its compact size and precise control capabilities, the HK-04G-L is widely used in various fields:

Home Appliances: Used for door interlock detection in microwave ovens, lid closure detection in rice cookers, cup installation detection in blenders, etc., ensuring that devices operate in the correct state.

Office and Communication Equipment: Used in printers and copiers to detect paper position, paper jams, or cover status; functional switching in communication devices.

Automotive Electronics: Used for detecting car door status, brake light switches, seat position limit switches, etc.

Industrial and Medical: Used for travel limit detection in automated equipment, position feedback in precision instruments, status monitoring in medical devices, etc.
