The TM2A616 is a TIME/MODULE repeat cycle timer featuring extremely flexible cam-based timing with modular construction that allows custom configuration for virtually any repeating time control problem. The timer consists of interlocking modules including a motor module with clutch, dial and knob module, a 10-1 reduction module, and multiple switch modules with rise and drop tabs or cam followers, enabling standard units with one through ten switches. The modular design allows the timer to be assembled in only one way through keyed connections, ensuring proper configuration. This timer is ideally suited for applications requiring predetermined sequential operations and repeating time control cycles where flexibility and customization are essential.
