Abstract: An electric switch includes first and second stationary contacts, and a movable contact for making an electrical connection between the first and second stationary contacts. The movable contact is pivotally connected to the first stationary contact by a pivotal connection for allowing the movable contact to pivot with respect to the first stationary contact about a pivoting axis such that in an open position of the switch, the movable contact is disconnected from the second stationary contact, and in a closed position of the switch, the movable contact is in contact with the second stationary contact. The movable contact and the first stationary contact are arranged in a first angle with respect to each other in the open position of the switch, and in a second angle with respect to each other in the closed position of the switch, and the second angle is greater than the first angle.
