Abstract
An electromagnetic relay switch assembly comprises, in combination, an electromagnetic coil, a movable plate of magnetizable material supported for pivotal movement between attracted and released positions, a drive wheel including a pawl member and being rotatable reciprocately in response to the movement of the movable plate, a carrier wheel having a detent gear and a ratchet gear. Each time the movable plate is moved from the released position to the attracted position, the carrier wheel is stepwisely rotated in one direction by the pawl member engaged to any one of the ratchet gear teeth. A detent pawl for avoiding the reverse rotation of the carrier wheel and a positioning member for accurately positioning the carrier wheel are also provided.
