Electrical contactors are electrical devices used to switch high power in power circuits. Unlike relays, contactors are normally directly connected to the load (current carrying) circuit.
Level switches, all types, is a generic search form for devices that are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action.
Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action.
Solid state relays (SSR) or semiconductor relays are semiconductor devices that can be used in place of mechanical relays to switch electricity to a load in many applications.
