Factors to Consider When Buying Armored Cable Alarm Switches
-
Durability: Look for switches with weather-resistant aluminum housing. This ensures they can withstand harsh conditions like rain, dust, and heavy traffic. A durable switch will last longer and require less maintenance.
-
Cable Options: Choose between armored or jacketed cables based on your installation needs. Armored cables provide extra protection in industrial environments, while jacketed cables may be more flexible for other uses.
