Add the DIP switch makes our M4-60 signal tower light more modular

We are currently upgrading our M4-60 signal tower light.
We modified the circuit and added a DIP switch.
Customers can adjust the sound and flash functions by themselves.

The following functions can be converted by the DIP switch:
1. Flash light or Steady light.

2. Continuous sound or intermittent.

3. Large volume or small volume

Moreover, the modules can be arbitrarily added or replaced.
(Such a design will reduce the inventory of the distributor.

More importantly, we maintain our price advantage.
