Any appliances and devices for small and low-noise relays and contactors will require general purpose relays. As they’re the simplest of the bunch, you can use them for basic controls as well as large-scale controls and devices, from buzzing systems in an apartment complex to alarms. They’re perfect when you only need one auxiliary contact and don’t require an overload relay. General purpose relays can place increased requirements when it comes to switching capacity, which in turn translates to switching voltage and service life.
