Home Alarm Wholesale Parts supply

This one might be harder to find. You need magnetic window alarm contacts. They MUST be NORMALLY OPEN style, not normally closed. This is backwards from a regular house alarm. You want the switch to close and make contact when the magnet is moved away from the switch. If you have trouble finding them, contact me I can get them here for $3.00 per switch. The manufacturer of the contacts I use is GRI model number 3030-12

Here is my local source for the contacts. He will ship across the US.
