Emergency stop for a linear actuator system, which comprises a housing (13) and an activation button (12) adapted for activating a circuit breaker and where the activation button (12) has a neutral position and an emergency position. The emergency stop further comprises a spring (19) for spring-loading the activation button (12) for retaining the activation button (12) in the neutral position, a latching mechanism adapted for retaining the activation button (12) in the emergency position once it has entered this position, and a release mechanism adapted to unlatch the latching mechanism. The spring-loaded activation button (12) is pivotally connected to the housing (13) and arranged to pivot between the neutral position and the emergency position. The spring-loaded activation button (12) comprises an arm (26,27) having one end attached to the underside (24) of the spring-loaded activation button (12). The housing 13 comprises a wall piece (35,36) adapted for engaging a free end of the arm (26,27). The latching mechanism comprises a protruding part (61,62) on the arm (26,27) and a receiving part (39,40) on the wall piece (35,36), said protruding part (61,62) and said receiving part (39,40) being unlatched when the activation button (12) is in the neutral position and latched when the activation button (12) is in the emergency position. The release mechanism comprises a reactivation button (14,15) movable between a first and second position, said reactivation button (14,15) unlatches the latching mechanism by disengaging the protruding part (61,62) from the receiving part (39,40) when the reactivation button (14,15) is moved from the first position to the second position.
