Braking circuit switch for an electric motor

An electrical switch, comprising:

• first and second changeover switches, said first changeover switch comprising first and second stationary contacts and a first movable contact for switching over between the first and second stationary contacts of the first changeover switch, said second changeover switch comprising first and second stationary contacts and a second movable contact for switching over between the first and second stationary contacts of the second changeover switch;
• a rocker comprising two lever arms and being mounted for pivoting between first and second positions;
• a plunger operatively connected to one lever arm of the rocker for causing the rocker to pivot between its first position corresponding to a non-actuated position of the electrical switch and its second position corresponding to an actuated position of the electrical switch, the first stationary contacts being associated with the actuated position of the electrical switch and the second stationary contacts being associated with the non-actuated position;
• spring means connected between the other lever arm of the rocker and the first and second movable contacts, the spring means being arranged on the rocker and on the first and second movable contacts so that when switching over between the first and second stationary contacts the first and second movable contacts are lifted off the first stationary contacts essentially synchronously in a direction toward the second stationary contacts and are lifted off the second stationary contacts essentially synchronously in a direction toward the first stationary contacts;
• and
• delay means coupled to the first movable contact of the first changeover switch for only delaying movement of the first movable contact of the first changeover switch when switching over from the first stationary contact to the second stationary contact of the first changeover switch, after the first movable contact has lifted off the first stationary contact of the first changeover switch, so that the first movable contact comes to rest against the second stationary contact of the first changeover switch later than the second movable contact comes to rest against the second stationary contact of the second changeover switch.
