Switch Driver

Feature Summary

  • Driven by standard TTL or CMOS outputs
  • Simplifies testing and prototyping
  • Inline electronics included in cable
  • Latching and non-latching versions
  • Compatible with 5V and 3V switches
  • Full schematics available

Quick and Easy Testing and Prototyping

This switch driver allows a switch to be easily controlled using a common TTL or CMOS output for testing or prototyping. The electronics for the control are built inline as part of the 1 meter ribbon cable. One end of the cable is equipped with an IDC connector, ready to be connected to our optical switches.  At the other end, a bare ribbon leaves the connectorization up to the user.

Full schematics are available in the sidebar for both the latching and non-latching versions of the driver board.  These schematics also serve as example circuits for controlling Luminos optical switches with TTL outputs.

Note: this driver is not compatible with a "center off" switch.
