Abstract
A centrifugal motor switch includes a base plate having a U-shaped fixed contact bracket and a leaf spring contact unit mounted to one side. The plate is mounted adjacent the field winding. The leaf spring is a flat rectangular spring plate including side deflection arms extending from a mounting strip and coupling arms connected to the deflection arms and to a central contact arm which extends outwardly. A wear pad is secured to the deflection arms and abutts the base plate to deflect the spring plate and locate the contacts. The contacts are secured to the fixed support and contact arm. A tab projects from the contact arm to the pad to minimize contact vibration. The bracket is formed of magnetically conductive metal and has side walls partially enclose the contact. A centrifugal operator on the shaft engages the pad and causes axial movement of the pad and spring plate with a rocking motion to rock the contacts.
