A safety brake for an elevator system including a car and a guide rail is provided. The safety brake is adapted to limit movement of the car in a first direction (D1) along the guide rail when in a braking state and comprises: first and second braking members adapted to be wedged against the guide rail when in a braking state; and an electromagnetic actuator, wherein the safety brake is configured such that: the first and second braking members are biased towards one another in a second direction (D2) substantially perpendicular to the first direction (D1); the first and second braking members are held in a non-braking state spaced apart from one another and the guide rail when the electromagnetic actuator is in a first state; and when the electromagnetic actuator is in a second state, the first and second braking members are moved into the braking state.
