Why Mechanical?

Turn the dial. Set the time. Walk away.

For straightforward timed override, a mechanical timer gives operators a simple physical interface without adding another programming layer.

No Programming
Set the required run time directly from the dial.
Mechanical Timing
The BMT-55 timing mechanism itself needs no external power.
Automatic Return
Counts back to zero at the end of the selected time.
Simple Interface
No menus, passwords or programming sequence.
