Don’t see what you need? Just ask! If we do not already build a device with the voltage, frequency or packaging configurations you require, we will be happy to design one for you.

Time Mark Corporation is actively engaged in the design, manufacturing, and production of special control devices under private label to OEM customers. Some are variations of existing Time Mark products while others have unique designs.
