Switch device structure

A switch device structure comprising a main body (10) and an operation body (20) displaceable relative to the main body (10), at least one electrical connection module (50) being mounted on the main body (10) and at least one elastic unit (60) being mounted on the operation body (20) to be displaceable in correspondence with the operation body (20) relative to the main body (10), each electrical connection module (50) including a fixed contact arm (51) formed with a fixed contact (51a) and a movable contact arm (52) formed with a movable contact (52a), each elastic unit (60) including a fixed section (61), a free section (66), and an intermediate section connected between the fixed section (61) and the free section (66), and the fixed section (61), the free section (66), and the intermediate section, defining together a geometrical configuration, the intermediate section of the elastic unit (60) including a base section (62), whereby an indentation (69) is defined between the fixed section (61) and the base section (62), and responsive to a position of the operation body (20) relative to the main body (10), the elastic unit (60) providing a releasable elastic push force to one of push the movable contact (52a) of the movable contact arm (52) of the electrical connection module (50) into contiguous contact with the fixed contact (51a) of the fixed contact arm (51) to change a circuit state thereof from a circuit open state to a circuit closed state, or make the elastic unit (60) separate from the movable contact arm (52) to a change the circuit state thereof from the circuit closed state to the circuit open state, wherein in the circuit closed state, the elastic unit (60) is in contiguous contact with the movable contact arm (52), and wherein in the circuit open state, the elastic unit (60) is displaced from the movable contact arm (52).
