Review on Morris Products 70332 Contacts Circuit by Sean Spence

Great little low voltage door switch. I used it to turn on the light in the closet when the door is open. If the lighting is rated for 110V AC, you will need a relay to switch the AC mains voltage, e.g. B. the Remcon Amprobe RC-120S Cabinet Type Relay Switch available from Revain. The relay is quite expensive and should be mounted in a metal case to provide additional heat dissipation, although if you're running a low power LED downlight like I am at 15W or about 0.15A, the relay is rated at 6.5A It's designed should never be stressed and you could probably do without the metal box but I used it for safety as I wanted it to last 20 years without needing extra attention. A little extra effort and expense upfront is better than hassle later.
