A timer mechanism helps provide the internal scheduling and switching function in a compatible timer enclosure, and this Intermatic T104M version is a 24-hour DPST 230 volt mechanism with a yellow dial using the T104M reference. Timer mechanisms are useful because they allow the working control portion to be replaced without necessarily replacing the full external enclosure.This part has practical value because the DPST 230 volt format is specific to compatible higher-voltage timer applications, while the mechanism-only design can simplify service in existing boxes. A properly selected Intermatic mechanism contributes to more dependable daily scheduling and more efficient restoration of the original control system.This type of part is especially useful when the original timer mechanism has failed, become inaccurate, or no longer switches the connected load reliably while the case and mounting remain serviceable. That helps restore timed control with a focused replacement approach.Installed in the proper application, this timer mechanism helps support dependable 24-hour scheduling and stronger long-term control performance. Intermatic T104M 24-hour timer mechanism for 230 volt DPST applications Features a yellow dial and mechanism-only replacement format Helps restore scheduled switching in compatible timer enclosures Useful when replacing a failed or inaccurate original mechanism Improves service efficiency and control reliability
