Abstract
A push-push (make-break) switch (43) including a thermally operated circuit breaker release is adapted for controlling an electric motor (42). The switch (43) may be employed by itself or used in conjunction with a standard control switch (41) connected to auxiliary contacts (15 and 18) which are normally closed but opened when switch (43) is activated. When switch (43) is momentarily activated, it becomes latched to continue operation of the motor (42) until the motor stalls upon completion of a task. The increased current draw of the motor (42) is sensed by a bi-metalic element (27) whose free end moves to automatically release the switch (43) and disrupt its continuity path. The switch (43) is in a compact, self-contained, design which provides various different operational features. In automotive applications, switch (43) provides convenient express operation of motor operated accessories such as power windows and the like.
