This Omron MY4ZH-US AC110/120 general purpose relay is hermetically sealed for Class 1 Division 2 approval, has plug-in or solder terminals, and is suitable for use in low current applications. This relay has quadruple pole double throw (4PDT) bifurcated contacts, an input current rating of 9.9 to 10.8 mA at 50 Hz and 8.49 to 9.2 mA at 60 Hz and a load rating of 24VDC at 3 amp, with an input of 110 to 120VAC. This relay's enclosure is approved by Underwriter's Laboratories (UL) as safe to be used in applications classified by the National Electrical Code (NEC) as Class 1, Division 2, hazardous locations where flammable gases or vapors may be present under abnormal operational activities such as a rupture or other faulty conditions. It has bifurcated contacts which is one contact that has been split in two for more stable mechanical operation, improved electrical contact and heat dissipation. This general purpose relay has plug-in terminals for connecting to a socket or soldering to contacts, and is suitable for use in hazardous locations.

Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.
