So to answer your question: Yes, you need to replace both switches. Just be sure the smart switch supports a 3-Way companion switch like the HS210 Kit. -The switch box you are going to put the switch in has a neutral wire (look for 2 white wires wire nutted together).
– Turn off power to the switches at the circuit breaker and using a tester, make sure power is off. …
– Using a continuity tester, check continuity between the common (black) terminal and each of the traveler terminals (brass colored) of each 3-way switch.
Thereof, Can you use a 3 way switch for a 2 way?
4 Answers. Yes, you can use 3-way (UK: 2-way) as 2-way (UK: 1-way) switches. It will work fine. Simply make sure the screws are different colors; you want the common terminal and one of the messengers; not both messengers.
Also to know is, How do you test a 3 way toggle switch? – Turn off power to the switches at the circuit breaker and using a tester, make sure power is off. …
– Using a continuity tester, check continuity between the common (black) terminal and each of the traveler terminals (brass colored) of each 3-way switch.
Subsequently, question is, Do I need a special switch for a 3 way? A 3-way wall switch controls a common light or set of lights from two separate switch locations. Two, 3-way switches are required in any 3-way application.

Separate the wires so that they are as far away from each other as possible. 2) Turn the power back on.
Do I need a double pole switch?
A 240-Volt Circuit Needs a Double-Pole Switch Circuits using only one hot wire need a neutral wire to complete the circuit, and the voltage between the hot wire and the neutral is 120 volts. … That’s why you need a double-pole switch, which is technically one that controls two circuits.
How do you test a 3 way switch?
– Turn off power to the switches at the circuit breaker and using a tester, make sure power is off. …
– Using a continuity tester, check continuity between the common (black) terminal and each of the traveler terminals (brass colored) of each 3-way switch.
Can you use a 3 way switch as a 1 way?
To convert a 3-way switch to single pole, one of the traveler wires is removed from the switch. In order for a 3-way switch to function as a single pole, the wires need to be connected to the common and one of the traveler terminals. … 3-way switches can be converted to single pole in several configurations.
How many switches can be on a 3 way?
It may be as shown at the end of the run, but it may be between any pair of switch boxes (as shown in a later figure), or even between the panel and the first switch box. You can use as many 4-way switches as you like.
