A switch includes a contact mechanism having at least one contact and defining a longitudinal axis. Actuation of a handle moves the contact mechanism transversely to the longitudinal axis between an open position and a closed position in relation to at least one fixed contact, whereby a contact spring loads the contact mechanism to seek the closed position. A support part is operatively connected to the handle and forms an abutment for support of the contact spring. The support part is moveable relative to the contact mechanism. Operated by the handle is a locking mechanism which is constructed to hold the contact mechanism in an intermediate position between the open and closed positions to maintain the contact of the contact mechanism at an electrically insulated distance from the fixed contact. A release mechanism interacts with the locking device for releasing the contact mechanism to move to the closed position.
