Sound-activated outlet control
The Clapper CL840R12 plugs into a standard wall outlet and switches connected devices on or off when it detects a specific clap pattern. Two claps activate the first appliance and three claps activate the second, allowing control of up to two items from a single unit. A Home/Away dial adjusts the microphone sensitivity for different room environments. The package contains one switching device.
Renters and accessibility users
This suits anyone who wants hands-free control of lamps, fans or a television without rewiring or installing smart-home hubs. It is not for installations that require hard-wired wall switches, integration with voice assistants or scheduled automation. Builders needing UL-listed in-wall relays or users who want app-based scene control should look at other product categories.
Dual-appliance clap sequencing
The defining specification is the ability to assign two separate appliances to distinct clap counts — two claps for one outlet, three claps for the other — from a single plug-in unit. This sequencing logic determines whether the device matches the user's control needs.

Questions about this item
What comes in the box and do I need to buy anything else to start using it?
The package contains one Clapper switch that plugs directly into a standard wall outlet. No extra parts are required; simply plug your lamp or appliance into the switch and it is ready to use.
The model is CL840R12 — does the number indicate different versions or capacities I should choose between?
CL840R12 is the single model offered; there are no alternative versions or capacity options to select from.
How does the 2-clap and 3-clap control actually work once the unit is plugged into a real outlet?
Two claps turn the first connected appliance on or off, three claps control the second appliance, and a Home/Away dial adjusts the sound sensitivity for the environment.
