I need to replace an illuminated 3 position wall switch that controls the outside front door light.In the \\\"up\\\" position the outdoor light is on. In the \\\"center\\\" position the toggle is illuminated,and the outdoor light is off.In the \\\"down\\\" position,the outdoor light flashes on and off as an emergency signal.Where can I get a replacement switch?The switch I have was manufactured by Slater and is 120V 300 Watt.Thank you for any assistance you may provide.Ron Hill
