Limit switch wiring diagram at ehow. A limit switch is used to control electrical devices by breaking and completing electrical circuits. The basics of limit switches. The wiring terminals are accessible through the front of the switch by removing a cover plate. The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white.

The black wire power in source attaches to one of the switch screw terminals. The normal open no switch wiring is shown below. Table of contents. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load.

This is commonly used to turn a table lamp on and off when entering a room. One improvement is to connect 1k to 47k pull up resistors to 5v and 100nf capacitors to gnd. The power input terminal is called the common terminal and is used to connect the switch to a power source. This is a completed circuit.

Furnace combination control operating temperature range limits. The control can handle 120v and 240v devices and can also be wired to control low voltage devices. Lets assume the load you are controlling is a light. And the sensing element can handle up to 350 0f.

Fixture wiring exits the switch box. The limit switch energizes the fan circuit when warm air in the plenum of the furnace reaches a preset temperature. The switch portion of this honeywell fan limit control can tolerate 190 0f. The cover plate is attached by two.

Circuit electrical wiring enters the switch box. The source is at sw1 and the hot wire is connected to one of the terminals there. Wiring a single pole light switch. Here a receptacle outlet is controlled with a single pole switch.

It has three terminals. The wiring in a non plug in switch is brought in through the conduit entrance at the bottom of the bodyreceptacle. The normal connected nc switch wiring is shown below.
