Omron PTF08A-E Track/Surface Mount Socket, With Finger Protection, For Use With LY1 and LY2 Series Relays
This Omron PTF08A-E socket mounts to a track or surface, has finger-safe construction and is used with LY1 and LY2 series relays. This socket has plug-in terminals for connecting to LY1 and LY2 series relays and is constructed to make it difficult for a human finger to touch the current-carrying parts. This socket mounts to a track or a flat surface and is Underwriter's Laboratories (UL) recognized for safety and Canadian Standards Association (CSA) certified for quality assurance.
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.
Omron manufactures and distributes electronic components, equipment, and systems for industrial automation. The company, founded in 1933, is headquartered in Kyoto, Japan.

frostwizrd asked Is there a switch that can be triggered by very low current, yet supply very high current?
I need to get a comparator to trigger a switch that powers an electric motor. My circuit is set up correctly insofar that the comparator outputs current when I need it to, but I need that output (barely .5mA) to be able to trigger a switch that can handle up to roughly 40A. I'm considering using a relay, but I'm not sure how to find one that fits those requirements; I don't have a great understanding of the various terminologies and characteristics of relays. =^( Any help here would be awesome. Thanks!
And got the following answer:
Without knowing much more about the problem (the voltage of the motor drive? AC or DC? Is switching time important? Hostile environment?) it isn't possible to offer an exact solution. However, here are some guidelines: 0.5 mA isn't very much. Very often switching circuits are set up so that the switching element sinks current rather than sourcing it; I suspect you may be looking at the wrong spec on your data sheet. Just reverse the inputs and you will reverse the sense of the output so you will maintain the same switching logic. -10 mA would be a pretty reasonable current sinking capability. If not, you will probably need to add a buffer amplifier to boost up the current capability a bit. Look into solid state relays; check the Digikey on-line catalog (Omron has a large line and there are many others). They typically require 2~5 mA to operate. For high voltage or high power equipment, if safety is any concern at all, solid state relays should always be in series with a mechanical relay or lockout switch because they can fail closed. For a motor that large you will certainly need to pay attention to a snubber circuit, or else you will likely blow the relay the first time you try to turn it off. For a DC motor, a diode connected across the motor so that it is reverse-biased when the motor runs is the best snubber. Be sure the reverse voltage rating is higher than the power supply voltage by a healthy margin and be sure the surge rating of the diode can handle the motor current. For an AC motor of that current, you should probably use a zero-switching type relay. If the voltage is low you might get away with back-to-back Zener diodes for the snubber. It is pretty high current for a resistive snubber. I know the Omron website has some application notes on snubbers for solid state relay circuits.
