Replacing a wall light switch with a Toggle Slide dimmer switch is an easy way to create a big impact for a minimal cost and perfect for renovations to match your existing light switches. Customize the light level in any room for any occasion. The Leviton Toggle Slide dimmer switches provide smooth, slide-action and full-range dimming with a separate On/Off switch that preserves the set light level when the switch is turned off and back on again.
