This may seem like an odd one for us, but pull-chain switches are actually pretty handy!
This is similar to the kind of pull-chain you'd find on lights and ceiling fans.
It's a simple SPST on-off switch (pull once for on, pull again for off).
This switch has 6" wire leads and a 10" pull-chain.
The switch can be panel mounted in a 3/8" diameter hole.

Features:

• SPST on-off
• Rated for 6A @ 125VAC
• 6" 18AWG Wire Leads  
• 10" Pull-Chain
