Home Improvements Replacing Modular Switches
If a fuse goes out or the circuit breaker is triggered each time you turn on electrical modular switches, the switch is most likely at fault and should be replaced. There are numerous kinds of switches, however the procedures to replace them for all of them are the same. It's possible to replace an alternative type of switch to replace the one that is damaged For instance, you could replace the normal switch with one that is a mercury (silent) type.
Make
sure that the power is shut off prior to beginning work. Remove the fuse
or activate the breaker for the circuit. Take off the two screws that hold
the cover plate and remove the cover plate. Unscrew the mounting screws
that secure it to the wall and then remove the switch.
Take
note of the wires for the switch. It'll depend on where the switch's
location is situated in relation to the remainder parts of the
circuit. The wiring for a three-way switch (where fixtures can be
controlled from two different places) is a bit more complicated and requires
that the switch you are replacing is wired the same method as the damaged
one. If space is available, move just one of the wires at a go from the
previous to the new one to ensure that you are able to get them right first time. If
you do not have space, mark the wires using the use of masking tape and a
pencil to help you keep track of which one belongs to the one you need to
remember.
Release
the terminal screws, and disconnect the wires from the switch that is
malfunctioning. Install the loops around the screw holes on your new
switch so that they can be tightened as you tighten the screws. Utilizing
needle nose pliers press the loops to close over the screws. Make sure the
screws are tightened. Install the switch inside the wall box and put in
the mounting screws. Reinstall the plate that covers the
switch. Bring power back for the circuit, by replacing the fuse, or
activating the circuit breaker. Next, examine the function that the switch is
operating.
The
backwired switch is accessible, and could be used to replace all
switches. Installation is basically the same as for outlets that are back
wired.
Dimmer
switches permit you to alter the atmosphere of your room that ranges from a
gentle, intense glow to a dazzling brightness, and every range between by using
a knob or slider. They also help conserve energy when they are set to a
position that is not full-on. Installation is the same as other switches,
with the exception that the control knob is turned to turn the switch on after
it has been installed and then the switch is re-installed.
