Omron’s popular B3F now comes in a 12 mm surface-mount package. These switches are perfect for long life tact switch applications. They have a switching capacity of 1 to 50 mA, 5 to 24 VDC (resistive load). The minimum applicable load (reference value) is 10 μA at 1 VDC (resistive load). Contact resistance is 100 mOhm max. (initial value) rated at 1 mA, 5 VDC, while the insulation resistance is 100 MOhm at 250 VDC.
