- Lamp Load:A type of electrical load imposed using incandescent light bulbs.
- Latching Action:See alternate action (or push-push). Actuator position typically indicates contact position.
- Leakage Barrier:A ridge or web molded into a switch housing between terminals or contacts to increase the surface distance between them.
- Leakage Resistance:Dielectric strength
- LED (Light Emitting Diode):A solid state device that is capable of emitting light.
- Lever Actuator:A lever that is attached to a basic switch to allow actuation of the switch from a place other than its button.
- Lever Lock:A part of the toggle on a switch that keeps the toggle lever from being moved accidentally. Its spring detent requires an outward pull on the toggle lever to operate the switch.
- Life Electrical:The life of a switch, controlling a specified electrical load.
- Life Mechanical:The number of cycles of operation that a switch will perform with no voltage applied to the contacts.
- Limit Switch:A type of switch used to determine the position of a moving component that activates it.
- Lockout Collar:Part of the switch bushing that prevents the toggle lever from being moved accidentally. There are many styles to allow for the desired operating features of the switch.
- Logic Level:An electrical load that simulates a computer input circuit, typically 5 volts at 10 milliamps or less.
- Low Level:A very small load; 30 millivolts at 10 milliamps.
