ABSTRACT:
A starter for a reversible motor has a single outer casing and one operating switch for controlling the forward or reverse rotation of the motor. The starter uses only ten pairs of electric contacts instead of the twenty pairs of contacts in a conventional starter. A safety means is provided which can turn off the undesired actuation circuit of the electromagnet. And another important feature of the starter is an adjustable screw with a coil spring sleeved thereon to assure the right movable contacts being closed in the starter without closing undesired contacts.
