25t125 5e4 Micro Switch with Roller Lever
Part Number: G15-10SM05-40-39
The G15-10SM05-40-39 is a 10 A SPDT snap-action micro switch with a roller-lever actuator for cam and moving-part sensing. It carries a 10 A resistive / 5 A inductive rating at 125 / 250 V AC, snaps at a 40 gf operating force, and is rated for 100,000 mechanical cycles. ISO 9001 and IATF 16949 certified, RoHS compliant, and shipped factory-direct from our Shenzhen, Wenzhou and Hubei plants.
Key Features

Typical Applications
This roller-lever micro switch is built for cam and moving-part sensing in automation and light machinery: end-of-travel limit sensing, industrial control sequencing, automotive mechanism feedback, and appliance door or drum position detection. The roller reduces friction and wear where a moving part sweeps across the actuator.
