Microswitch Activation Spring Ø3.7×2.9×3mm

This small but essential spring activates the microswitch in Eureka coffee grinders, ensuring reliable on-demand or timed grinding operation. When the spring wears or loses tension, the microswitch may fail to engage properly, leading to inconsistent grinder activation or no response when the portafilter is docked.

Replacing a worn activation spring restores proper microswitch function and ensures consistent grinder performance.
