Switch for AC sync. motor - has blocking lever ensuring that rotor rotates in one direction only

摘要

The switch has a one-sided rotor rotation blocking element that is only pivoted in when the motor is started. The switch is closed via two rods which rotate the switch's rotary component about an angle in the same direction of rotation. The switch's spindle locates in a roller body or a pin body or a similar part. The blocking lever of the motor spindle has a flexible leaf spring and acts against the action of a spring via a second leaf spring or an additional elastic movement transmitting device when moving into its active position.
