Z-Wave modules can be used with a variety of switch types. This guide explains how most modules can be used with Momentary, Toggle and 3-Position switches.
Toggle (Bi-Stable) switches latch in position. For instance when you press the switch to On, the switch physically stays in the On position. These are the standard light switches you'll find already fitted in your home.
You can use these in two ways, depending if you would just like On/Off control of the light or you would also like to control the light's brightness from the switch
Using a toggle switch in this configuration will enable you to manually control the light On and Off, just the same as a normal On/Off switch.
As strange is it sounds, a toggle switch can also be used with some Z-Wave Dimmer modules to control the light's brightness. Although this may at first appear a little unconventional.
You'll need to check the manual for your specific Z-Wave module and see which device Parameters need changing to support Toggle switches.
Momentary switches, also known as Retractive, Mono-Stable or Bell-Push, only remain in the On state while you press them, they return to the Off state when the button is released. This doesn't mean that you have to keep holding the button to keep the light on. The module's internal controls automatically keep the light on when the button is released.
Note: Some modules will cycle the dim level while you are holding the switch ON
A 3-position momentary switch has 3 positions and is also known as an ON/OFF/ON switch. It normally stays in the central (Off) position, you can then press the top or bottom parts of the switch to move it into the On positions. As this is a momentary (retractive) switch, it only remains in the On state while you press it, it returns to the central Off state when the button is released.
Note: Not all Z-Wave modules fully support 3-position switches, if yours doesn't then it's still possible to use them but they will operate like two separate momentary switches attached to the same input
You'll need to check the manual for your specific Z-Wave module and see which device Parameters need changing to support Momentary switches.
There are a variety of vendors offering momentary switches, these include Scolmore, MK Electric, Clipsal and British General.
For Vesternet's videos and testing we've used the Scolmore Click Minigrid range. They are available in different finishes and look good.
As they are a 'minigrid' range you select the components and then assemble them yourself - this enables you to select just the configuration you want:
Figure 1: Minigrid Faceplate and Switch Ingot - unassembled
Figure 2: Minigrid 3-gang switch - assembled
Figure 3: Minigrid 3-gang switch - rear view
For this example we used Scolmore Click Define components:

You should only use the switch types shown above with Z-Wave Dimmer modules.
Other switches such as conventional dimmer switches and 'electronic' switches should not be used.
Conventional dimmer switches cannot be used as they will conflict with the dimming action of the Z-Wave module.
These are switches such as touch sensitive switches or switches with LEDs.
They cannot be used with most Z-Wave dimmer modules as the switch connections cannot provide power to the electronic switch.
