Hall Effect Sensor Housing Unit

Small housing to fit a hall effect sensor used in my home automation system. The sensor it fits is 31mm long X 13mm wide X 14mm high. The lid is there to cover the mains voltage terminals if required, I had to clean out the little "hooks" on the main housing to get the lid to slide into it properly and click into place. I used a Dremel with a thin cutting disc to clean out the hooks.
