Study Notes
Switch Types
- A toggle switch is operated by physically moving a small lever or toggle.
- A flip switch is commonly found in home lighting systems and is flipped up and down to control the lights.
- A slide switch is designed with a flat mechanism that is moved horizontally to establish or break the circuit.
- A toggle switch is commonly operated by a flat mechanism that moves horizontally.
- A rocker switch is characterized by a rocking motion for operation.
- A double-throw switch is designed with two levers that can be inclined in different directions for control.
Relay Maintenance
- A common indicator of potential issues with a relay during preventive maintenance checks is unusual or abnormal operation.
Relay Operation
- When a Normally Closed (NC) relay is energized, the armature contacts open.
- A toggle switch moves back and forth to control the state of a circuit.
- In a relay circuit, when current flows through a Normally Closed (NC) switch, the armature contacts open.
Relay Functions
- An Off-Delay relay delays turning off the circuit after the switch is turned off.
- An On-Delay relay delays turning on the circuit after the switch is turned on.
Switch Issues
- A common consequence of dirty contacts in a switch is intermittent or unreliable operation.
- A common issue caused by dirty contacts in a switch is intermittent or unreliable operation.
Test your knowledge on different types of switches by identifying the type of switch that can be controlled by a small lever or toggle.
