strange switch in garage

[John Arnold]

46 year old home. Anyone know what type of switch this is? It's in the garage next to the manual overhead door. The conventional switch is for the garage ceiling light.

It's an X10 switch, a remote switching device that transmits to a receiver some where else.

Dom.

Thanks Dom. Strange to find a high tech device like that in a house that still has 2 prong receptacles.
