Abstract: A stemless operation mechanism includes a case, a first moving component, a second moving component and a detection module. The case includes a first accommodating area, a second accommodating area and a partition portion used to provide an airtight isolating function. The first moving component is movably disposed on the first accommodating area and includes a first magnetic unit. The second moving component is movably disposed on the second accommodating area and includes a second magnetic unit located on position corresponding to position of the first magnetic unit. The second magnetic unit is cooperated with the first magnetic unit to generate a magnetic attraction force or a magnetic repulsion force. The detection module is disposed adjacent to the second moving component, and adapted to detect a movement of the second moving component for determining an operation behavior applied for the first moving component.
