Ultra Reliable Powerline Control Based Switch

The WS1E Wall Switch ELV Dimmer is a high quality home automation dimmer switch that is capable of transmitting and receiving digital commands and status over the existing powerlines.

Designed specifically to control electronic low voltage AC lighting ballasts or transformers.

  • FET Reverse Phase Dimming for electronic low voltage control
  • True Rocker Action
  • 200 Dimming Steps
  • Multi-way Control via "slave" switches up to 1000' away
  • Scene Control for up to 16 scenes
  • Variable fade rates from instant ON to 1 Hour
  • Security flashing mode can be triggered with a UPB transmitter


Tapping its paddle style rocker switch will turn on and off the lights while holding it down will fade the lights up and down. Separate light levels (anywhere between 0% and 100%) can be chosen for single-tap and double-tap events. Sixteen different fade rates can be selected – from instant-on to one hour – to give you ultimate flexibility in controlling how fast the lights fade on or off. The dimmer function can also be disabled, turning it into a switch, to allow the WS1E to turn on and off non-dimmable loads such as fluorescent lights and motors.

Three-way (or multi-way) light switch functionality can be obtained by connecting one (or more) RWS "remote" switches (sold separately) to its yellow traveler wire.

Receives From the Powerline

The WS1E will accept powerline commands from any UPB-compatible transmitter such as the PulseWorx Keypad Controllers, Timed Event Controller, Interface Modules, Approved Third-Party Controllers, Touch Screens, and even other WS1s. Each WS1E can be a member of up to 16 Links/scenes with the capability to store a pre-set light level and fade rate for each scene. Each pre-set light level can easily be adjusted by the homeowner using the innovative PulseWorx manual programming method.

Transmits To the Powerline

The WS1E can also be configured as a two-button transmitter. Select from a list of commands to be transmitted when each rocker button (top or bottom) is tapped, held or released. This allows the WS1E to remotely control other devices or update indicators (LEDs on our keypads).

Easy To Configure

Like all PulseWorx devices, the WS1E can be initially configured using PCS's freeUPStart Setup Software tool. UPStart enables configuring such parameters as Network Name, Network ID, Unit ID, Room name, Device name, default on light levels, fade rates, LED colors, dimming disable, auto shut-off time, etc. as well as test the operation and communication strength of the device. UPStart has the option to configure an entire network off-line and then download the information into the devices after they are installed in the home.

NOTE: Wallplate not included.

UPB PulseWorx Lighting Control System

An integral part of a complete PulseWorx Lighting Control System, this device uses the patented UPB powerline communication technology (invented by PCS) to reliably communicate with any other UPB-compatible devices over the existing house electrical wires. No new wires are necessary, thus making PulseWorx perfect for retrofit situations. When initial configuration is complete, a single push of a button is all you need to activate any group of lights (or virtually anything else that connects to AC power wiring) throughout the house simultaneously.
