The model 455 operator uses a bimetal element to control the lights.
Automatic Doorman located in Palisades Park NJ should have the switch.
You can contact them via R&K Mockler Garage Door Manufacturing

If you can't get the switch from them, give me a shout at
and I'll dig one up for you.
Happy Holidays to all!!!

Does anyone have the wiring diagram for the lynxx model 455 garage door
opener? If I can identify the switch, I will search for a replacement.

I was advised that the time delay light switch is broken. The problem is
that the light stays on permanently.

I tried contacting my local Overhead Door-it seems that they don't want to
sell me the switch without a service call.

Your assistance is appreciated.
