| Should the contacts used on windows be visible or recessed in the frame? Does the burglar seeing the switch go elsewhere because he now knows you have more than just a sign and some decals? Can the burglar defeat the contact just because he can see it? Some people cannot tolerate the sight of normal surface mounted contacts or feel unsecure because the burglar knows what's there. Other people feel secure seeing the switches because the burglar knows I really do have a system installed by a professional. Surface mounted switches often are easier to install. Although the price for installing recessed switches may be higher with some companies, our prices run the same for either switch. One hype concerning recessed switches is the size of the switch in a wooden door or wooden door frame. If the switch is recessed in the frame, you can not see it when the door or window is closed. As long as it fits the frame properly without overlap, it does not matter what the diameter of the switch is. In steel doors and steel door frames, the switches and magnets need to be isolated from the metal so they can work properly. These switches and magnets are usually inserted into a 3/4 inch or larger hole. The larger switches are usually used. However, plastic adapters can be used to hold a smaller switch in the hole. |
